upgrades to my Toyhauler

Hi. Some might know me from a few other forums(this is a copy from another forum). I have been lurking over here for a while.

So I have this custom stacker toyhauler. I know it is not specifically an expedition vehicle but I am a big fan of expedition vehicles and tend to built things that would easily work in them. Thought I would throw in my work in case anyone wanted to check it out, or get some inspiration. Constructive criticism is always welcome.

I guess to start I should throw up what I am working on.

A little perspective of how big it is. That is my 2001 F350 crew cab 4X4 long bed tow rig.

I'm in the process of installing insulation and paneling, but with the cold weather I decided to take a break and work on the Fridge Freezer cabinet and bed.

Started with the Fridge Freezer cabinet. This will hold both on slide out drawers with some storage. The microwave is going to be moved back to the kitchen countertop per wifey request, which leaves room for a drawer for storage next to the freezer.

Also behind that drawer there will be room for the Beer faucet area that will have an access door to the outside. That will come later and be built out of Stainless, with a drip tray, lighting and 4 faucets. I'm probably just get a couple of ice chests and cut holes in the top for the kegs.

Roughed out the frame to start.

Then put it in the trailer to test fit. Everything fits. I should be getting the drawer slides tomorrow and will finish it up this week or weekend. I also need to figure out what to do about counter top. Wife wants butcher block style, and I agree. Ikea has some pretty cheap, just need to figure out if they are deep enough.

From the outside looking in. I am thinking of skinning the whole thing in white like the other cabinets. There will be room on this side above the freezer for a radio, 12V outlets, and a couple of 120V outlets.

Then I started work on the bed. This will bolt to the side wall in the very back and fold up out of the way. I went a little too big on the tubing(14 guage) so it's heavy, but at least it won't break. :p

Started by building the two frames, then welded on the tabs for the hinge.

Tested the hinge.

That all worked so I welded on the legs that will bolt to the side wall and tested the height. There should be enough room a the wall hinge for a little storage box for night light, laptop, iPad, whatever.

It's tall, but it will work. We have always preferred sleeping on air mattresses so we will continue with this. If I want to I can always get a nice mattress later and store it upstairs. I took the measurements from the air mattress we have and added a few inches. I built it high enough so that when we are in camp the dog crates and storage bins will easily slide underneath out of the way. I still need to build the legs and have not completely figured out how to make them fold up and down and secure in both locations. I want to put in some bracing when folded out so it is really stable. .

Got most of the fridge freezer cabinet done. Will replace the temporary top when I figure out what I am going to put on top, or more specifically what the wife wants. Also have not decided what to skin the sides with.

I want to put a radio on the side by the door and maybe some 12v and 120v outlets.

Built legs for the bed. Just need to figure out the fold up braces. I'm thinking about welding some nuts into the side of the legs and using small heim joints on the end of some all thread or tubing with threaded inserts.

Still have to add the plywood top, attachments for the wall and paint.

And for comic relief, did you know a 10' piece of 1.5" square tube will fit in a Prius?

I do now. :wings:

The hauler is huge! Very cool. Post some pics of the inside and how you access the upper space. Does the rear open for access?

I like the sliding drawers for fridge and freezer too. Looks like good work.

Yeah the rear is a typical fold down door like any toyhauler, just better built.

the upstairs is a large ramp that lowers down and you drive quads or dirtbikes up there, then lift the ramp.

Downstairs unfinished.

Good shop of the back.

And just because it's not big enough inside the wife wanted a California room for the awning. We also have the outback awning and california room for the rear ramp. All that stuff hooked up makes this thing HUGE.

The updates have been driven by the last trip we took to Johnson Valley thanksgiving of last year. It got down to 20 degrees, and the trailer has no heat or insulation. Wife said never again until it has heat and insulation.

In addition to the fridge/freezer cabinet and bed I will be putting in a furnace(not sure how big I need) and another large cabinet that will hold the furnace, a bunch of drawers, and a TV. I also need to work on winterizing it, since all the tanks and the pumping are outside. I am looking to build some enclosures for the tanks, replumb everything with some heat tape and insulation and either put the water pump inside or in an insulated ammo can.

Lurking around here for good ideas. And I do what to say thanks. :)

looking good. that musta been a great night in 20* weather. My wife said never again will we go if we can help it if it will be below 40*, as one of the last few times we went it was 12* overnight, and our propane heater kept shutting off due to low oxygen level (doesnt help we were at 9800 foot elevation)

good work with that toy hauler, i am envious.

Thanks.

I've been mulling over in my mind what I should do for heat. A basic RV furnace makes a lot of sense, but there is always the issues of efficiency. I've been looking at hydronic setups, even making my own, but in the end the simplicity, availability, and cost of the basic furnace just make too much sense. Probably the biggest problem I have had with selection is sizing. I keep getting different answers. A good friend who is a mechanic at an RV place says a 5,000 BTU unit will be enough, but i am not so sure. I may go with the single 5,000 BTU unit, and if it is not enough add another one.

Decisions decisions. :)

are you looking at propane powered or electric?

I'd say maybe 5,000-7,000 BTU should be adequate, though it wont heat it super quick but it will work. if you are using propane, make sure you pay attention to the altitudes as they dont work well over i believe it is 8,000 foot elevation due to the lack of oxygen.

first thing I would do IMHO is just get some home insulation and thin vaneer panels and insulate that trailer. that way it does its best to keep the temp decent.

Thanks on the sizing advice.

Insulation is in process. The walls are only 1" deep, and with the upstairs ramp I can not build them out. I will be building out some of it where I can, but a large part of the middle will have to stay within the 1" depth. I am going to be putting up some light wood veneer over most of the interior. I have plans for some thicker plywood where the bed will be, as sort of a head board, with a small box for storing some stuff. The bottom 1-2' will be thicker and probably be skinned in either white veneer or diamond plate.

We have propane so that is the obvious choice. Right now all I run off the propane is the hot water heater and stove. I have two 10lb(I think) tanks so I should have enough for a week in the desert. If not I will add more.

One thing I am looking at doing is getting a large 120V AC space heater of some sort. Since we are typically in the desert with few people around running the generator for a while is not a problem or nuisance. I figure if I can get the trailer up in the 70s F with the space heater and set the furnace to maintain at say 55-60 F it should just fine. We really don't need to maintain 75F overnight. We have pretty good sleeping bags, and a bunch of puppy heaters to keep us warm.

One other project I am going to do, due to the height inside, is an air circulation setup. There is a spot just forward of the hinges on the upstairs where two of the structural steel pieces go across the width of the trailer and leave sort of a channel. I am going to get a bunch of small silent fans that will fit the width of that channel and use them to circulate air from downstairs to upstairs. It will be low profile and should create enough air circulation to even out the interior.

This weekend is an off weekend so we can go meet my new niece in Oregon, but the weekend after I will be finilizing the bed bracing(will probably just do something simple for now and upgrade later if I need to), the wood for the bed, the mounting for the bed, and paint everything. We have to clean out the trailer as the last weekend in April is the Southern California Homebrew Festival, and I plan on hanging out with over a thousand of my homebrewing friends and drinking a lot of beer. :wings: Should be a good field test.

ok I am truely envious. you got a nice toy hauler AND you are goinna do a big drinking fest.... NO FAIR! I will finally get my well deserved beer in about 2-3 months!!!! YAAAAAY CANT WAIT!!

as far as what you are planning, I truely believe you are on the right path! I cannot wait to see the end result. Is your truck diesel or gas? I am hoping Diesel or the aerodynamics of that trailer will KILL your fuel mileage!

Diesel. And it still kills the mileage. I get 8-9 towing the trailer, regardless of how loaded it is.

Funny story, on one trip to my parents in Oregon we were heading up the 5 through southern Oregon and on one of the hills I crested the top at about 50, slowly accelerated to 55, but once I started going downhill I put it in neutral(6-speed manual) to coast and the wind drag from the trailer dropped me from 55 to 45 almost instantly. :Wow1:

I've looked at options for better aero, but there just isn't anything I can do. I just keep reminding myself I will get there eventually, slow down and keep it safe. Surprisingly the trailer tows like a dream.

lol ok, i'll take your word for it!

My guess though is maybe due to turbulance.

Basically it's because it would be too far from the front plane of the trailer. If it was closer it would work, but there is no practical way of doing this.


You want to play, you gotta pay.
