Finally got started on this project. This was a homemade camper built from the ground up by my dad and brother. I've started the process to see if I can save it and plan to make it my mobile hunting cabin.The plywood roof is ok. However the luan sides are delaminating. So I've started by removing that first. Here's what I managed to get done today.

This is what it originally looked like.

fun

too much bed

Agree. That was part of a slide out that went over where the four wheeler is. I've done away with the slide and plan to turn the bed sideways, cut in half and turned into two bunks.

i bet it turns out great

Looks great

Here's a look from the front. Lots to do. Checked 1/4"treated. $36 a sheet. Hardi board 24. Hmmm.

That will be a blast

do we get to make comments ?

Hardi plank is pretty heavy

Yea, that hardi board will add alot of weight and when it gets wet is like wafer board

Comments are certainly welcome.

I was wondering that it may be brittle as well and prone to cracking. Plus sealing the cut ends may be problematic. Looks like plywood might be the best choice. It's pretty light now. On the left rear was a hatch that was used for a little air conditioner. I have a plan now to seal that up and install an ac inside the lower cabinets on the back wall. Then when you want to use it, you just open the cabinet doors. The rear bumper would help support it.

Do you have metal working capabilities
Some 24 gauge metal siding would be really effective
IMHO

I don't. My shop is set up for wood working. I thought about aluminum interlocking siding especially being a couple of miles from the salt, but I don't know enough about everything I'd need to be water sealed. My thought was to use 1/4 inch treated plywood with construction adhesive and staples. Then a few coats of a heavy paint like Cabot Deck Correct and then seal the joints with 5200. That would eliminate any outside moldings. The glued plywood would also help stiffen the walls.

This is a cool project. This is better and prolly more fun than building your own deer stand.

Watching intently!

that is a really good plan
it will definitely shore up your structure
