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...
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.
