So previously I had loaded down my truck with 4125 lbs of retaining wall blocks. I did this a couple of time and she handled it just fine. But Saturday I went to new levels of pain and suffering for my suspension. I drove almost 2 hours and loaded her down with 5670 lbs of concrete paving stones. We hand stacked 270 patio blocks in the truck and I put the midgate down and it had 900 lbs resting on it alone.It was in instant "redneck drop kit". The truck was a wee bit washy on the highway to say the least. And at 78 miles each way to the landscape supply store I only burned about $35 in gas. Not bad for a big block. Some where in the range of 10 mpg. The landscape owner said I can't fit 2 pallets in my truck, so I took it as a personal challenge. He said you'll break your truck. I told him that if you don't treat it like a truck the it's just a really big car. He walked away confused. But when he came back and saw the truck loaded he was amazed. I told him I didn't get 2 pallets in, I got 2 and a 1/4 pallets. He just chuckled. My Brother in law put a pallet in his Tacoma and my father in law had 3/4 palet in his Tacoma. It took 2 trucks wit 6 foot beds to accomplish what I did in a truck with compact bed. My hat's off to the GM engineer that made my truck. I took some pics of the truck loaded down. I'll post them when I get home from work.
