Thanks everyone. So much info. Only a diesel will be considered as we had a gasser but that was 20 yrs ago so no real comparison onlymyDuraMax has spoiled me towing.
Never thought about the side mount radiator & we have looked at a few with rear radiators & Iwas all ways wondering HOW do you work on these
We are retired now but probably won't full time as I have other hobbies ,this is DW's idea so its just a go ahead and write the check thing, ya'll know life will be easier to just roll with it. I am happier with a 5er than any of our other rigs but admit this one is our 1st new one. & not used by others . I may have to bump up the budget a bit.
