I'm looking for a sanity check here. Tonight I loaded up the bed of my truck with cut firewood. Don't ask why, but tomorrow I'll be driving my loaded truck about 300 miles, primarily via interstate. I see in the manual that the maximum payload rating is 1510 lbs. I don't know how much the bed-load weighs, but the rear is sagging pretty much. I wouldn't think it exceeds 1500 lbs, but loads like that really add up.
I've actually done this before, but cared less about the truck then, and try to treat it better nowadays. Didn't seem to have any issues the first time, but still figured I'd consult the 'experts' here before casting off. For the record, the tires are virtually brand new (Michelin LTX M/S) as are the shocks (Bilstein 5100).
Any advice? Am I a dumbass for doing it, or am I concerned for nothing? For the record, I don't plan on exceeding the speed limits much, and I've checked the tire pressures and set them just barely above door jam stated numbers.
