RE: Trailer?
My 2 cents:
I've been pulling this 6 X 12 with a Tahoe for the last several years. One foot extra tall, side door.
Soft-ride torsion bar supension makes a big difference for trailers, as they bounce on rough roads more than a vehicle, and a spring suspension can really beat your planes up.
I have it fitted with a heavily-built 2 ft wide work bench, drawers, vice, etc. up front, and I experimented with several fancy set-ups for the back 10', but settled on two big removable shelves, so (counting the floor) I can carry two large and one medium-sized planes fully assembled. Interior lighting and external 120v power plug are very important, for charging and tools.
I shuddered at Jon's comment that if you need more than two planes at an event, you probably shouldn't be flying the third one. All Too True!
However, friends and I will share the trailer, go to the same event and we disassemble and pad-pack the planes to fit more. This helps reduce the pain of the horrible gas mileage I get (Tahoe drops from 16 mpg freeway to 9 mpg pulling the trailer!). I don't know if the V-front would help with mpg. Doesn't sound like it listening to jonkoppisch.
