Trailers and 5ers require a vehicle to tow. I would guess a solid 50% of the posts associated with trailers are derogatory comments about the manufacturer of tow vehicle used by a previous poster. Mixed in with that 50%, and probably add another 45% are questions about "Can I tow this" and derogatory comments about the GVWR of the tow vehicle used by the previous poster.
5% of posts are relevant to an actual camper or camping experience. That makes for about 52,000 postings total... or roughly equivalent to the Class A forum.
Or at least that's just my experience as the owner of a foreign brand grocery getter who has had ZERO issues towing.
