The fenders are 15 inches wide. That gives me room for 35-37 wheels and tires. And a tremendous amount of room on the outside of the trailer to put things.
the comments are spot on, but as you move along you learn things. The tank, which is for grey water, fits the trailer better there and the generator fits better in the back, when you are tying them down. I will incorperate a regular holding tank in the next one. I have room for one now, but making the rear bumper 2X2 versus 4X4 will allow a good sized tank. Just had never thought about it before. I will have to put a pump on it doing that, which adds to the cost most likely a couple of hundred dollars. Also would need a skid plate as it would go through the floor.
Most just drain grey water on the ground. I am not into that, but the shower drains on the ground, so I guess it is okay.
I doubt the production trailers will have a spare on them unless ordered that way. Most likely a jet ski box on the front, additional batteries, solar cables, hose, chocks and other items. That is what the side box is for now. Plus the jet ski box is a lot cheaper than the locking side box.
I will mount the rotopax in front of the trailer along the bottom. I like that idea alot, but do not have room to do it on this one.
Again thanks guys, great ideas and comments.
