single - even being single, build it with two doors - a door on each side - more than often I found the campsite will dictate what side of the trailer you will be accessing in and out on!! Plus, for resale, even with it being a 4x8 it is more sellable. Something else you may look at building as a compromise is 4-"1/2" X 8. One of the problems with a 4x8 is the mattress size. With a 4 ft you either have to have a mattress made to 'fit' it or find a mattress that can be cut to fit - a mattress 4 "1/2" wide is a common size = 'FULL' size -- as is a 5 ft = 'QUEEN' size. (both sizes very 'common') Am speaking from the experience of having now owned both sizes and yes, the 4ft wide was just "fine" for one person and you know, sometimes this 5ft one I now have is just a bit "TOO WIDE"!! when trying to reach out to grab something

that 1 extra ft is just a bit too far.....!!!

this 1/2 ft idea could be the compromise....... something more too think about.......
