I've had my Frontier since I bought it new in 2002. It's mostly used for monthly-ish trips around the state with the bed loaded two Rubbermaid tubs high bed full. Once every other year I go on a week-long camping trip with a rider that involves lots of gear, and I'm looking to buy a trailer. I have hauled a 5x8 trailer before and the only time it was a problem was when a transmission seal wasn't seated properly and blew the transmission. I didn't have to pay for that rebuild. That was two years ago.
