Which pick up to buy for towing big fifth wheel?

OP has not returned, after starting 2 same threads, to give any further information.

With the many opinions, most with a DRW, say you should have one, and the SRW towers say not needed. This is the same general pattern, when this question is raised.

Maybe the OP will return on one of his threads, with more info on the actual FW he is asking about.
