Greetings, foamlings!
This thread is where I am hoping to work out a plan for building my small travel trailer. I am aiming for a garageable standy (probably made stoopy by the garage door clearance, but hopefully helped by the fact that the tallest person camping in it is 5'8") with a full-size mattress crosswise in the back and a small kitchen/storage area in a v-nose on the front. I am going to try to avoid the complexity of a drop floor or a pop-up roof. I've just begun constructing a 1:6 scale model and will post about that as I work through it.
I have the NT Ironton 5x8 trailer and a flexiride axle for it. The axle will hopefully help me gain some headroom since I can drop the ride angle on it. I also already have a fridge: an Engel MT-45 that I am planning the kitchen around.
My tow vehicle is the RAV4 in my avatar. 3500lb towing capacity.
I am currently considering:
A "sandwich" wall construction: thin plywood inside, 2 x 3/4 foam, then PMF on the outside. The 2 layers of foam will be easier to procure and allow me to easily insert 1-by wood into the inner layer where I need it and use a sort of rabbet joint at the edges.
A gently curved roof constructed mostly in the common inside-out method: inner skin, spars with foam between, but then a thin (1/2"?) sheet of foam and PMF over the top as the outer skin.
A tongue extension to provide a bit more space between the v-nose and my tow vehicle.
Robust solar power for boondocking--probably flexible panels on the roof. DC power only for the trailer interior.
I'd love to hear your thoughts! Now to figure out how to do pictures...
