I've been wanting to build another trailer but longer and better than my first box trailer. This time around I'm going to change a lot of from the last one I built. Spread axle is on the board for changes and I'm thinking of an auto hauler kind of like monster truck and NASCAR trailers. A single rear fold down door/ramp. Which has me thinking I haven't planned this out very well because the deck needs to be lower? Especially if I want to be able to drive cars unto it. A 6" high deck isn't exactly ideal but I still want to be able to use the tamiya chassis that I have.
