I checked out the ram website and figured out the hauling capacity for my truck (~1600 lbs). Then I got to thinking. Last year I filled up my bed with some compost for my garden, and I drove it home (about 10-15 minutes) without even thinking about the weight. The rear end sagged down a few inches, but everything else seemed fine. I just took it slow.
I'm guessing I had about 2 cubic yards of compost in the bed, and I think that can weigh over 2000 lbs depending on moisture.
Is there a possiblity that I may have damage my suspension in any way? It's been a year, and I haven't noticed any issues.
P.S. I don't plan on doing this again.
