Off Road Trailer building tips M8A1 Ammo Mule style

[M8A1MuleBuilder]

Hi Everyone,
I see a lot people building there own trailers so maybe I can help some build a M8A1 style trailer?

I built a jig to build my off road trailer, perfectly square and perfectly level. I then built a rotisserie style frame holder to spin and weld the frame in any position and also to weld all joints in a flat weld position.
I used 1.5” x 3” x 16 ga. Rectangular tube strong and light weight.

Also, this makes it super easy to wire the electrical.
I use 5/8” square tube as conduit to run all my electrical wiring through, this way driving over rocks and bush will not effect the electrics.

I used a 3” axle tube rated at 7,000 lbs with 10” electric brakes. 5 lug on 5” bolt pattern.

This trailer weighs about 850 lbs. with the side wall vertical struts it is very strong!!!!!!! The side walls and tongue wall are like steel GIRDERS on a metal building...exponentially stronger.

2 rear bumper leveling jacks
