Those cladding mounting holes are going to be relocated to the receiver tube since the tube bumper behind the cladding will either be modified or go away entirely. vt_mav will be the guinnea pig on the installation instructions (my tube bumper has already been cut up).
We won't know until the final design of the hitch if we'll have to include some spacers for the cladding bolts.
Sue, I think that your cladding alignment issue was related to some sharp corners on the hitch plate that needed to be knocked off. If we were going to continue with that design, I'd make sure that we fixed that problem.
