I'm building a small offfroad trailer, something like this one, and I'm wondering what sizes and shapes of metal would be right for the tounge and frame. Also, how long of a tounge? does 48" past the frame to the end of the coupler sound right? Im new to fabrication and could use some advice, any advice really. I want it to be 40" wide and about 48" long (I know HF makes one that size but it's too light weight). I plan to have fixed sides about 16" to 18" high with two cross bars just like a roof rack that will make the sides more rigid and hold a roof top carrier over the top, and there will be tailgates front and rear on it. The front tailgate will rest on the tounge when it's open making a sort of table. I think a standard 2" hitch ball will be fine offroad, not really sure though. I've seen some 2" ball / pintle hybrids that look interesting.
Does anyone know of a good local source for trailer axles, used or new? I'm looking for a used trailer with a 5 x 4.5 bolt pattern that I can cut up, but so far CL is full of junk, if anyone has one or just an axle I'm interested.
Thanks!!
