I have a 2005 4x4 8 foot bed with the 4.7.... Whats the payload ? i think a yard of rock is like 2400lbs

 

the bed isnt the problem i would worry more about the rear suspension...and the fix for that is bags!!!! or just make 2 trips case solved

 

i did that with no bags. it was about 1800 pounds. and it was saggin bad!!! and my tires werent looking too good. but it made the whole 3 miles home.

 

Yep, volume is not the issue, it's weight. Payload is WAY under what you'll be carrying. Having said that, my truck is sitting alongside my house right now with 1800# of floor tile and "stuff" in the bed.

 

well i have an 03 4.7 with the regular bed and i had a 1/2 yard of gravel in the back with 5 100 pound bags of cement on top and i also had a trailer hooked up with another 1/2 yard of crushed limestone with another 5 100 pound bags of cement on top it handled but ill tell u my front end was so high up i could see the dodge logo on the front of my truck lol and i was going like 25 miles and hour

 

I have an 02 reg cab 4.7 with the 8 foot bed but mine is 2wd so the extra drop in the front helps level out the load. I have put 3000 pounds of gravel in the bed and while it did considerably drop the bed i was able to make the 30 minutes ride home doing 65 the whole way. I most diffinatly would not do this on an everyday bases but just remeber, its a truck.
