Making the bed sound so miniscule but having my 5x10 with dual doors and now the 4x7 with its single door making the bed without my helper is a real pain.
I have no fear of being trapped in a blazing inferno of a tiny trailer, with enough motivation that little plywood box would explode with the force of a big fat guy in blind panic making his exit
I have had past experience with the passenge side unlatched door on Chubby merrilly swing in the breeze at 70 MPH while running down the interstate. Luckily none of the camping goodies escaped into the roadway. For that very reason I placed the only door on the 4x7 on the drivers side somewhat contrary to the general concensus of the forum. I felt it would be easier to keep an eye on in the driverside mirror.
As to placement of the door , when I get to the campsite I can simply spin the trailer to place the door wherever I want it.
I am sure if we both go camping she is going to insist on taking Chubby because of the 2 doors.
As I was building the 4x7 she complained about the one door design. I explained there would be no climbing as I would be last in and first out as always and if a sudden middle of the night desire struck her I would be a gentleman and get out to allow her egress without obstacles.
I ,for one ,do not think there is any one answer to any aspect of tiny trailer design. Different strokes for different folks.... I have multiple trailers and each are different and are used at different times of the year and weather conditions for different reasons.
