Personally, I'd like to see dealers holding tech clinics - putting an X up on a lift and demonstrating to newbies maintenance we can do ourselves, pointing out the low points of the vehicles (diff, xfer case, etc.).
Perhaps giving classes on driving off-road (proper inflation pressures, stuck extraction, etc.).
It would be nice to have dealers sponsor monthly Xcursions, maybe supplying some Nissan hats, perhaps occasionally supplying lunch (subs (grinders/hoagies for those on the east coast), chips, drinks). I know this costs money, but it could possibly come out of discretionary funds, and would definitely be good PR. If Nissan wants to build a relationship with buyers, and wants them to come back for repeat purchases, this would certainly help! In addition, the sponsorship could provide a channel for feedback on likes/dislikes about the vehicles!
