hey, i'm new to the forum and looking for some info as the title says. i currently have a 2007 dodge ram 2500 quad cab with hemi.

i no longer really need a truck especially a 3/4 ton. i was just wondering how the tahoe and burbs are towing loads like 6500-7500lbs? real mpg numbers city/highway/towing, are there any major issues with either of these suvs?

any help would be greatly appreciated, thanks
