Re: 67-72 C/K/T-40's-90's!
I sure like that truck. Ans,what a classy combo that will be pulling a camper. I can't say from experience,but 7 mpg doesn't sound off to me.I can only compare with what you say about rpm @ 65 compared to my 3/4t 4wd that is at that same rpm at 65. It gets 12.5,maybe less going over 60,but it's much lighter. So,I'd guess 7 would be possible.
