The sizes and dimensions for my trailer I borrowed from
The Mil spec trailer website, what they did'nt have sizes for I scaled off
the photos when enlarged.
I set my axle to the rear of the trailer, as per their design to give me a longer wheel base, so reversing is easier.
With the container full and cool box full, its about 40-60lbs on the hitch.
I looked at the ex military ones too, theres a mob in canada that'l ship down to the states, they have a bunch of newish design ones.
issue with the ex military ones is the weight, as they are over designed.
With mine fully loaded I can still lift a wheel off the ground
The cheapest built ones i found in the US were the ones Trevor mentioned earlier in Cali.
To me they are the way to go for expedition and or trips, you arrive, park, set up and your done, you can then cruise around the local area
without tons of gear on/in the truck..
