I gotten in arguments about gvw, someone claimed you can register a vehicle for what the max combined load rating on the tires. My reply is throw some 22.5's on a Toyota and try to pull a 52' trailer and not get pulled over. You can upgrade the suspension and brakes but what about the frame?

Unless something is obviously unsafe I don't see too many issues unless you're running commercial registration, then they can be picky about everything. This one is a classic Attachment 14113
