My wife and I are looking for a Suburban 4x4 for a 3rd family play vehicle, with some long road trips, daily driver/hunting/fishing, etc. We have an Accord, and Titan, but need more room at times with 4 teenage girls & 3 large dogs. Im having trouble deciding which route to go. Im fairly mechanically inclined (Jeep builder), but not sure if I should go pre-91 or mid/late 90s. Those are the choices due to our budget of $3500-4500. I dont want anything over about 150k miles, so most of the ones Im finding in our price range are mid/late 90s 2500s with 454....a few great deals there - but 10-11mpg..?, and some 1500 4x4s with a few more miles. Found one '89 2500, 134K actual miles clean, in budget... This older guy(former GM tech) says this one gets 15-18mpg with a 350/Turbo 400...is that possible?? Anyway, I plan to put 33s or 35s on it. I thought the 2500s would allow for more tire room w/o a lift, but not sure. Main thing is I want it to be solid... not too fragile. I may play a little hard with it at hunting camp. Gas mileage is a factor, but not the deciding one. Wife want some creature comforts, so cant be too much like a cargo van. Any help and thoughts are GREATLY appreciated.
