Ok I?m getting an itch to get an enclosed trailer to do a mini toy hauler and sleeper conversion. Goal would be to have a small off road or dual use motorcycle, my paramotor (basically a 2?x4.5?x4.5? brick), a place to sleep and enough storage to not have to load my suburban constantly. Based on some rough sizing I think I need about 70 square feet of space. This is not a portable home and I am not looking for extreme comfort. Use would be to go for meetups or 2-3 day trips, and have it ready to roll with minimal packing. At campsites the motorcycle would come out. I would like to limit it to 3000 lb total so it?s towable with a Maverick or other smaller truck.
I watched a bunch of YouTube videos but there are a few things that I am not sure of. I was wondering if any of you have small trailer experience or enclosed trailer experience and what you would recommend. And let?s face it the knowledge on this forum is excellent.
For instance here is some things I am still working through.

Aluminum vs steel? Aluminum is not much lighter.
Do they rust a lot? Will aluminum last longer?
Side and dirt roads, do I need an off road package?
Ramp vs doors, with one or two motorcycles I can bring a small removable ramp or is a drop ramp the way to go. Which setup is better?
Is 0.030? skin really better than 0.024??
Is rivet less construction important?
Anyone have experience with a walk on roof? (It would be neat to have an upper deck but not sure it?s worth it?
7 foot vs 6foot width. Is 7 foot that much worse to tow? (7 foot by 10 foot long might be perfect but not sure about the additional width)
Any experience with modular interior setups? Going with my son and two motorcycles for a trip would be easy if the interior can be reconfigured.
Any other important things to look for?
