Trailer Weight

I was aiming at 1200# & ended up at 1660# dry on the scale (oops!). Your frame is stout, but if you build with an eye to weight & strength, it should be possible. Where lots of us get in trouble, we think in terms of house building not trailer building. Take a look at the framing used in older trailers to see what works. I'm amazed at what has worked with 1x2's, staples, 1/8" panelling & glue. Not in a teardrop, but in full size standys which still roll along well enough. Take a look at some of the build logs to see how different people approach the weight issue & see where they ended up.

I overbuilt my cabinets, extra panels weren't necessary, 1/2" where 1/4" would have worked well, but as a former cabinetmaker, it's what I knew that worked. Should have thrown away about 1/3 of the panels, but I wanted a strong build (I got it, 20,000 miles & no problems) so I chose to err on the side of strength. There's no right or wrong here, just compromises which add up to a build in the end.

For my modified benroy "smiles to go" (build journal in the sig) I used 3/8" BCX for the outside walls, 1/4" lauan for the inside walls, with 1x2 spacers and R5 3/4" foam board sandwiched in the middle for the walls. Roof was 1/8" birch two layers more r5 foamboard in the middle.
Everything was glued, and stapled, then staples removed. Outside was epoxied with fiberglass tape on any and all seams.

So far 4 years later its till water tight, gets at least 1k miles a year if not more, and has been stored outside its entire life.

Weight was 860 lbs loaded for war, and pulled by a small hatch back for the first two years. Never had issues with wind, or strength.
