Looks great all hitched up! I've had my eye on that same tongue box for a while. I really like the idea of line-x'ing it, instead of depending on the cheap harbor freight powder coating.
Looks like you went with a standard trailer ball hitch. Did you make a second full length tongue? Also, where did you get the weld on trailer jacks?
I agree, the cheap paint on the HF box won't last. I have their other wider tongue box on my car hauler and it looks pretty bad after only a year.
The best thing I did was LineX the entire trailer, top/bottom/sides, and all the smaller components on the trailer.... It basically encapsulated all the steel and I won't have to worry about rust, unless I rip or damage the LineX.
As far as the hitch, I made a standard 2" ball DOT rated hitch for towing on the street, if you look in my thread you'll see I made the jsherb 3 axis hitch. I added a 3' extension to the 3 axis hitch so I can extend the total length to 7' (that's why the 4' extended tongue). I'm planning to build a second 3 axis hitch but a twist to jsherb's design. Instead of welding the T using the 3/4" diameter tubing welded to the 5/8" tube, I'm going to have the piece that connects to the 1" grade 8 bolt (the T) machined from billet steel stock and thread/weld that to the rotational axis. I'll post some progress pics when I get to that.
The jacks are also from HF. I took their standard 2K lb tongue jacks and added 12" to the length using 1 3/4" .120 wall DOM tubing (jacks come with the weld-on tab). The trailer sits 27" from the ground to the jacking points. The HF tongue jacks only extended to 19 1/2"... A little short
In the mean time, I picked up a set of 35 x 1250 x 15 BFG Mud Terrains today. Going to throw those on this week... As if the trailer isn't tall enough with 32's:jumping:
I need to get going on changing out the gears on my '05 TJ... The reason I built this trailer. But with 4.10's and 35's, it's lost a little power for towing... Throw some 5.13 gears and I should be good to go.
