Teardrops n Tiny Travel Trailers

Last year I completed my first teardrop build, a 5 X 8 Benroy on a HF frame pretty much following the plans on this site. The build went well, and we have enjoyed several trips with it so far. In using the teardrop, however, it has become apparent to both my wife and i that what we would really like is at least a small standing area of at least 5.5', 6' would be better. We are willing to give up the galley and pretty much all built-ins except those needed for structural integrity in the interest of weight savings. My maximum is 1000 pounds, and I would like the build to be under 800 if possible. A design like the Wanderer 10 really appeals to me, but I haven't been able to find any plans or build journals for anything similar using foam.
So here are my (beginning) questions for you foamie guys and gals:
1. Is a design like the wanderer 10 doable in foam, and how much do you think it would weigh? The wood version has an estimated weight of 1400 pounds, but I expect that includes some cabinetry that i probably won't include. Do you think this could be done under 800 pounds?
2. Can you suggest any available plans or build journals for a small stand-up like the Wanderer 10?
3. How hard would it be to use the existing Wanderer 10 plans and just figure out how to substitute foam for the wood?
Thanks in advance for any input you can give me. I am just in the brainstorming stage right now and will welcome any suggestions you care to give.

I have seen were a guy built a teardrop with a Benroy front and a drop floor behind the axle. With a HF trailer you would have a drop floor about 4 feet wide and 2 1/2 to 3 feet deep. One could do some type of raised roof on the back(like a wild goose or big galley hatch with trucker tarp sides ? )
Just some thoughts.

I think it could be done. Just doing a quick calculation of material for the basics, Foam, trailer, and OSB, it looks to be about 450lbs. That would be for trailer, floor and walls only. Hardware, windows, doors, interior items would start to add weight at that point. You still have 350lbs. to work with though and that is a lot. If you keep it simple should be pretty easy. Now remember to also add all your personal items that you take with you too. I would just look at a few of the builds here.

The Camp Capsule has a stated weight of 874lbs and is a nice looking little trailer. Good luck and keep us posted it you start to build one. Oh, with pictures too.....

Don't forget the "Big Pink" foamie. I don't remember the final weight, but that can be adjusted through scaling and paring down to just the essentials.

Did I hear someone mention "The Big Pink "?


It ended up weighing about 900 lbs, but that is with a frig, AC, popup tent, toaster oven etc....
It also has 2 floors, the original plywood floor, and the queen size bed platform made from Pine.
I have 2 premade windows, 2 premade hatches, and a model T (?) metal bumper.

900# sounds perfect .... Seems even large foamies' can be LIGHT !!!
