When it comes to The Mount-n-Lock Heavy-Haul'r RV Bumper Replacement Kit - Aluminum - 4 inch - 500 pounds # MO94VR is 0.100 inches thick per the manufacturer.
This bumper will fit the I-beam, S-beam, tube, and channel frames. The flanged frames must be at least 4 inches tall x 3 inches long. Non-flanged frames must be at least 3 inches tall by 3 inches long. The maximum capacity of the bumper is 500 pounds when evenly distributed.

I contacted the manufacturer regarding the measurements you were needing on the MORryde 14-3/4" Shock Absorbing Equalizers # MR34AR. I have included a diagram labeling some of these measurements. They did not provide a measurement for the thickness of the bracket but stated that it is made to fit into a standard frame hanger. view full answer...
Tires like the Kenda Karrier 225/75r14 # AM10256 are going to be 1.2" taller and 0.7" wider than your 205/75r14 tires, so as long as you've got that much clearance to the fenders (at the top) and trailer frame (on the inside), you can use the larger tires as a replacement.
You'll also want to make sure you've got about 3" of clearance from the top of the fender to the tires as well, when changing tire sizes. view full answer...
