Best bet is just a plate style one.
That's the best alternative. You'll need a set of rails which should run you about $200 plus installation but that really is your next best bet over the B&W.
When I bought the truck it had rails in it. The previous owner worked in the oilfield and hauled an RV, however he didn't leave the receiver. Only the rails.
What year/model truck?
2005 Dodge Ram 2500 4x4
There was a used B&W in the classifieds on here a while back. Also may check a salvage yard.
I didn't think about that. That is a great idea.
