Here is the reason: I have a special needs (mentally disabled) 11yo boy, and he can't handle being at places like other people's houses, events, stuff that we may want/need to go to as a family. When he was little, we took the 3rd row out of the Excursion, some blankets and beanbags and he was happy. Went through a few years of darn near unable to travel due to anxiety, but now actually likes traveling, but not necessarily being places.

Really this all got green lit after 2 funerals this winter that would have been crazy easier to go to as a family had we had this.

I am building this to be 100% usable all 4 seasons, including the coldest of MN winter weather.

I'm not starting blind, been RVing all my life.

I'm also not starting blank. I have a 22ish foot bumper pull (2010? IIRC, or somewhere around there) RV that is junk due to water damage around the popout, but other than the rotten floor/wall, the rest of the mechanicals are find and so I will be tearing that unit down and taking all the parts.

Some features and items of note:
  • As said, usable all 4 seasons, including fresh/waste water.
  • Will have a toilet.
  • Needs a shower, but maybe one of those toilet-in-the-shower showers to save space?
  • I think on-demand water heater, but I'm not set here.
  • "Build in" generator, or at least a portable generator that has a dedicated spot and wired up to the panel with a generator interlock. Will tie into the unit's propane system.
  • Propane system will be dual 30 pound cylinders, as a note. The donor unit is 20 pounders, but obviously all the mounts/plumbing will work, just not the cover, but that is no biggie.
  • Auto stabilizing and/or leveling system. I may home brew this one, not sure yet.
  • Build in mounts/cables for starlink mini.
  • Looking at roof solar and better than average battery capacity with a good size inverter so generator only needs to run full time if using the air conditioning.
  • I actually have a brand new roof RV air conditioner in the shed with soft start I could use that would almost be oversized. Reasons.
  • Fresh water lines/tank/pump will all be in the heated living area. Designed to be very easily drained.
  • This will NOT be a drop-down suspension like ice castle type "RV" trailers.
Things I'm looking for input on specifically:
  • I want to be able to sleep in it, but that is not the primary use at all. That said, he loves snuggling in beds, so it will have at least 1 full size twin out all the time. I'm thinking the "couch" could be another full size twin or full with crazy large back pillows to make it comfortable as a couch AND bed? I dunno, regular convertible RV beds suck, so looking for options. A queen solution would be great for the Mrs and I, but that isn't a requirement. The only likely purposeful camping would probably be myself and my oldest (and maybe youngest) to go winter camping.
  • I'm thinking about an arched roof instead of flat. We had a Coachman like that, was nice will still being nicely towable. Makes the roof harder to transition on the front though.
  • I'd LOVE to not use rubber roofing, so open to options here. Fiberglass? Once piece aluminum?
  • Siding: fiberglass or look at the RV aluminum siding?
  • Wall structure: what is the light weight DIY solution here? I also need this well insulated, so most likely going to spray foam it as that is the most dense R value I can think of. Steel wall studs?
  • Waste water: Small tanks in the heated living area? Regular tanks, but insulated and heated? Regular tanks with a bunch of salt dumped down before use?
  • General layout. This will be a blank slate build, so layout ideas are always nice.
  • Donor RV has 2 doors, so there is that.
  • Windows: is it worth trying to figure out a 2 pane solution, or just re-use the single pane RV sliders? Make it easy to plastic them in the winter and call it good? Custom plexiglass winter second pane? Have 3D printer, have CAD, but not sure I want to put that much time into custom 2 pane RV type windows. Yes, I know they already exist, but $$$$$
  • I don't need a lot of storage, but want to be wise with the space available. Anything that will be stored will be in gasketed totes to keep them clean and fresh, just like we do at the cabin.

Subscribed to see if you post pics and document the build. Someone had built a small tow behind in the past and posted on ARF.com. Looked good.

I'll get the teardown done this spring, but I'm sure construction will be a next winter project.

One of my favorite YouTube channels is  Peak Mountain Camps.  

If you go through the videos, they show how they build their camps.  Very solid design, IMO.

You could get some ideas and incorporate them into your build.

Best of luck.

We built on out of a cargo trailer one time .  It was way cheaper, but still “travel trailer quality”

If I was gonna do serious traveling, and build myself again, I’d buy aluminum horse trailer with torsion axles and use it as the superstructure.  Will end up heavier, but also won’t break shit on every trip .

On demand hot water makes it better .

My needs are very similar.   I keep looking at this one.
