Update
So, I've done some work the last couple months. This is all just in the rough-in stage, mind you...still lots of finish work to be done yet. I was going to have to press this into service and travel cross country, hence the rapid and rougher fab than I would normally do, but plans have changed again, so I can slow down a little...
My first project was cutting in a side door. More than that, I wanted to gain some much-needed head room and have the entry way double as a shower (eventually - for now, it's just a door). So, I cut down into the overhang and then lowered the floor a tiny bit more and now have a little over 6' of height in the entry (I'm 5'9", so this is plenty - including a showerhead in the future!).
Began by framing the opening
Next up was the technically simple, but emotionally difficult task of whacking a hole in the side...
I ended up using a pivot hinge, but will likely change this to more normal barrel hinges as I lose some opening with these.
Door framed out and clamped to hinges
Had a brand new camper latch assembly that got used.
The footwell / shower basin...
Skinned with left-over interior siding...drain to be added later
Next up, basic fridge work
Picked up a nice Norcold 3-way - older so it's all manual switching and it works great!
Next was a battery tray between the side door and rear wheels
It's set up for 2 x 6V golf cart batteries - eventually I'll likely step up to Trojans or similar, but for now while I'm sorting out the system and learning what I want/need, I'm using these from Rural King - 208AH and $70 - hard to beat.
After that, I decided on a 5K BTU window AC unit - it'll share some venting with fridge.
Again, used spare interior siding as the exterior duct work
I also cut in the Marinco stainless shore power exterior connector - it's not hooked up yet - waiting on my 3+off rotary switch
Then I moved on to a semi-temporary generator mount. I intend to cut the generator into the right rear overhang, but was running out of time and needed to get it mounted in a useable way, rather than a perfect way. I had a pivoting hitch coupler, added a hitch-mounted vice mount and some steel and came up with a lockable, but swing-away hitch mount system so I can open the doors.
I opted for the 3000W powerhorse sold by Northern Tools - supposed to have slightly more surge capacity than the Honda, every bit as quiet, and $800+ cheaper. For what I'm doing, it should work great.
Last thing I did was a propane tank mount. Nothing holds a 20lb bottle better than a milk crate and I happened to have an old-school all-metal one. It's not the prettiest, but it's sturdy and works well.
That's it for now - next priorities are getting the AC/Fridge duct work finished up and sealed properly and moving on to the basic house electric system while building the cabinetry for the sink, cook top, and storage....
