i have a dodge 2500 Hd 4x4 quad cab with an 8' bed ..hemi engine automatic trans and 410 rear and gvw of 8800#s and load range E tires .. truck weighs 6250 with me on the scale .... this is the best truck i ever owned ... it has carries my '96 starcraft roadcraft 8'slide in poptop ... i can NOT even tell when it is there .... my owners manual aslo says this truck is not designed for use with pickup campers ... i think in this case it is a lawyer thing ..... this camper has also been hauled with a '95 dodge 4x4 1500 360ci engine and load range E tires, that i installed air bags over the springs/axel, this was done more for sway control than load carrying ... the gvw for the slide in is about 1700 #s ... recently i bought a travel trailer, so it is time this spring for the pickup camper to change hands ... before you ask, i live near lancaster, pa
