Work has been busy, but I was able to find some time and get the shop guys onto my track trailer. I'm undecided on the way to secure the tires. Which is better (see photos)?

With the dual bar retainer, only 41" of the 48" total trailer width can be used because of the tube bend. However, if I go with this design I will have them make it with no bends (miter cut it). They are also making a combination one for me to see. Essentially, there is two bars 6" apart connected to the vertical peice that is tightened to the main frame - yeah I know, I can't explain worth a poop.

I've got a plastic type tool box, 3x3x2, a 180 cubic centimeter nitrogen bottle and my ez-up 12X15 tent to add.

Anyway, which design do you think is better? Why?
