I've been looking for a cargo trailer to convert for double-duty; mostly cargo, some camping. I came across a 1974 Avion trailer that's half the price of a cargo trailer; it's been emptied, with the walls/floor/ceiling re-finished. So now I'm trying to figure out if it'd work for me.
The trailer is 8x31ft which is a good foot wider and 11ft longer than I've been looking for, but I might just go after it if I can fit it with a door for loading cargo (probably in the back). Does anyone have any experience or suggestions for adding a large door to a trailer like that, a 36"+ RV one or double doors?
