Buck,
Looking real good...you want believe this, but 8 months ago I ripped two by fours in half to use for the steel to make a mock up trailer and what I put together looks very similar to yours. On the right side of my model I am extending two of the side uprights above the top rail by about 4 feet to make a side support for an awning and lighting when camping.
Since your design is about 90% of what I am planning, can you give me some critical dimensions I don't have to compare to what I have on paper:
The size of tire you are using, I assume it is a 16" rim, as it came from a FJ
It's a 265/70/17.
The distance from the inside of the widest part of the tire to the metal side rails
Roughly 2.25" from the inside of the tire to the frame.
The height of the top of the 2.5" tounge rail when the trailer is level.
The top of the tongue 25" from the ground.
Is the axle centerd on the main box frame? Or is there a bias towards the rear? ETA: looking at your picture of the trailer standing upright, looks like you are biased to the rear for a tounge preload, I calculated using the 2" steel tubing weight to have the axle 60/40, for my 6.5' long main trailer box, the axle center line is 2' 8" from the back.
I did it 60/40. The box is 72" long so it's roughly 43" from the front.
I am planing to run the main tounge member all the way down the center to the back and having a receiver hitch on the back side.
I am having trouble finding wheels. I want a bolt patter to match the 4Runner. I found some new rims at Pep Boys that look like an old American Racing Outlaw, made by a company called Ion, never heard of them, but if I go with a 16" I will need to set my spring pads such that the 17" 4Runner spare will fit with out rubbing the side rails.
My other concern is having the trailer ride level or slightly above when unloaded. So that is why I need the tounge height, I don't have a mock up axle yet.
Mine truck is lifted so I got the 2" adjustable lock and roll hitch
I even thought about getting a Toyota tail gate for the rear gate, and building the trailer around that.
Sorry for the questions, but if I lived near you, you would have a lot of free help on this project. I actualy designed the trailer before I purchased my 4Runner!!
Thanks,
