Why weld when bolting is better (and costs less)? 

Common square tube RV bumpers weren't designed to carry much cargo weight as they are typically attached with just the thinnest of welds.  Sure, you could pay someone to beef up the factory's bumper welds, but at $80 per hour, this gets expensive fast!  Plus, your thin-walled bumper is still "hanging" from the same attachment point as before.  Instead, with only a drill and a couple of wrenches, you can install a superior solution in minutes.  Be safe; be smart.  These inexpensive parts bolt directly to your RV's frame and support the bumper from underneath, stopping the metal fatigue that leads to bumper failure.
