Yes, I know it would look like a coffin.
So, anyway. 7' box. Can't have over 30 or so lbs on the tongue. How long does the tongue have to be? Is there a width to length thing for tongues and wheels?
My tire centers are 46" apart and axle to tongue is 72"
Currently it tows just great but I figure it might change with a 7' box on top.
My biggest concern is to lessen the pitch (up and down motion) on the hitch.
Any engineers out there? Can't have a squirrelly trailer on a bike. My belief is that the rear of the trailer going left will cancel the front of the trailer going right and so on. (At least if the box is centered on the axle). I know it will probably be slightly forward to give me the required tongue weight.
I apologize now for rambling.
For those interested in my trailer idea:
The roof would fit on like the lid on a shoebox and I would add a 2-3 foot strip of canvas between roof and walls. It would look something like the old VW vans with pop-up tops.
It occurred to me that if I added 4 corner holders 1/2 inch or so deep on the bottom interior and 4 of them on the lid, I could use 4 broomstick sized rods to keep the roof up. Mounting them in each corner would prevent the roof from swinging around much and the canvas tension would keep the wood rods in the holders (holes drilled in wood or metal). I think that would work great as long as it didn't rattle a lot in the wind. The canvas would be one piece from RR around front to LR with a flap at the back to climb in and seal it. It would attach with snaps or something to the outer lip on the box and inner lip of the lid.
