Extended E250 Gypsy Supermoto Build

Hi guys!

I'll make this quick.

Intro story: Basically want to build a van that I can sleep in and take around the various places that I will be working the next few months. I want this van to be ultra low profile, that way it doesn't draw any attention. The DRZ will be my DD and the van will be just a resting location. Eventually all of this content will be moved to a website that I will build. But I need to figure out how to use/host wordpress first!

With my obligations and time constraints, I only had 5 days to put everything together. It is what it is.

Without further ado..



Van:
2006 E250 5.4L V8 Extended Body with 230K miles (Ouch!)
Solar panel mounted on roof
Maxxair RV vent fan
Interior LED lights that are rated for a couple thousand lumens (it has a PWM dimmer attached)
Dual receiver 1000 lb rated motorcycle carrier
Hidden triple battery bank (Holding 1 battery currently)
Laminate flooring and white Masonite walls for that IKEA-esque touch
Reflectix on every surface
2" Styrofoam on every surface
Fiberglass stuffed in doors and wheel wheel crevices
Limo Tint for the peepers

Bike:
DRZ400SM w/ usual upgrades

Future Plans:
Steel Partition Barrier: (If anyone is selling one on the West Coast, please let me know!)
Closeouts between ceiling/roof
Custom made cabinets/storage
More batterys/panels
Simple Ladder rack on roof
Small Refrigerator/Sink/Stove setup

Time for the pictures, I will order this chronologically.

Maxxfan Install:

The van already came with an older RV vent installed, meaning that most of the work is already cutout for me. Pun intended.

For sealant: I used three types of sealing methods. Rubber weatherstripping, vaccum bag tape (Don't laugh!), and clear silcone.

Fastening: I used the supplied hardware from the manufacturer. Basically a couple of pan head cap screws.

What to watch out for: The van roof is not perfectly flat. It has stiffening channels stamped into it. What this means is it difficult to seal this area "straight up". The way I fixed it under a time constraint is to take strips of rubber and "stack it" it to create a flat datum. I applied RTV in between every rubber to insure it doesn't leak between the rubber strips. If I had the time to do it properly. I would build a small mold on the van and pour castable RTV to create a custom gasket for it. But....whatever.

Dual Receiver Hitch Motorcycle Carrier:

Logic:

I was very skeptical of a standard class III motorcycle carrier hitch surviving a 6000+ mi round trip (East coast to the West coat) with a 350 lb bike strapped on it.

A standard hitch carrier, in my opinion, does not safely constrain the bike. A single piece of cantilevered box tube will be going through multiple bending modes( pitch, roll, and yaw). I can already see a fatigue based failure happening with those things.

So I fabricated two receiver hitches that bolt on the frame rails. This seriously minimizes the bending stresses seen by the part. It is VERY sturdy and only weighs about 30-40lbs. I have no problems putting a larger bike (500+ lbs) on it, with the exception of it's effect on the van's driving dynamics. I drove this setup loaded for about 1900 miles, and I am very happy with it. I can take the van 85+ mph and not think twice about the supermoto falling off.

Materials:
I used 3"x .125" WT Angle and 2" x .125" WT flat bar for the platform. 2.5" x 3/16" WT Box tube for the female receiver hitch material and 2" x .25" WT box for the male hitch material. .25" Plate for the frame rail bolt-in mounts. Everything is MIG welded with the exception of the endcaps, those were TIG. I wanted to ball hard with that part.

Picture time!

Below: Made the drawing for the bolt-on brackets in CAD


Below: : While I was waiting on my buddy for lunch, I had some extra time on my hands. For shiggles, I did a VERY rough FEA on the part to get a ballpark idea of the stress values. Honestly I should have just done a free body diagram and do some hand calculations.....but whatever.... I like pretty pictures. Should be good to 1000+lbs. I did not do any fatigue hand calcs, but it SHOULD be good enough for my 350 lb bike.

Below: Made some things out of angle to constrain the wheels. Please do not use the as your only constraint, use a rachet strap around the van doors as well


Below: Wheel constraint w/bike attached.


That's all I got for now.

Next Time:
Insulation
Battery Tray
Wall/Floor
LED/electronics install

Nice!

Have you thought about getting a bike cover for when its on the back of the van?

This is what I have been dreaming of. A camper van with a moto rack. I sold :( my tarded out xr650r for some unknown reason and have been missing it dearly. Hopefully if everything works out I'll buy a wr250x and a van or tacoma with flippac.

Excellent work on the bike rack!!!
I'll be stealing some of your ideas for my future double carrier... Have an XR650R and a little 150 for the better half to haul.
Then, I'll probably need to build a small one for the front bumper when the kids are old enough to ride... :D

Also, can you post a couple more pics of how the receiver(s) mount to the frame? Looks like they just mount to the end of the frame rails?

I aplogize for the long response time. The last few weeks have been hectic.

For the bike carrier: A picture is worth a thousand words.:sombrero:

Bike%20Mount%20on%20Frame.jpg

Interior:

Basic Idea: An IKEA-esque setup on wheels.

Insulation: Reflectix everywhere, 2" Styrofoam On floor and walls, and 1/2" on ceiling. I know that the ceiling is probably the most critical, but I'm space constrained.

Floor: Got some extra flooring from a cousins renovation for free!

Wall: Standard white wall masonite. I chose this material due to it's color, weight and price. It's pretty hard to beat.

Lights: LED light strips and PWM controller from the internet. I can post up links if anyone is curious.

Pictures:
Below: I drove it for a few weeks.


Below: Ripped it all out and cleaned it.


Below: Add some Styrofoam.



Below: Start with the flooring.


Below: Now with walls. Note: The fit and finish is not that great, but I was under a huge time crunch. I'll write it off as that...:ylsmoke:



Battery Tray:

Made this out of some flat bar and angle iron. It bolts to OEM holes in the van. It can hold 3 batteries. Currently only running one.

Below: Battery Tray outside of van.


Below: Battery Tray installed.

You've got me thinking about all the extra batteries I could add on my rig... :D

The two I'm running are marginal. A few more, and some solar panels and I'd be set.

Great job. Looking forward to updates. Could you post the LED info. I always say with a build you can never have too much info.
