My choices of a DD truck I'm looking to buy sometime soon. Here in town is a '94 K3500 regular cab with the 454 and 4L80E. It would be excellent for my duties of DD and pulling a trailer or hauling stuff in the bed. The downside is lack of interior room. My other choices are the '91 V3500 crew cab and '91 V2500 Suburban. What do you guys who have any of the above have to say about mileage out of each? I want all to be automatics and only the Sub to have the 5.7 liter engine. I just want to know ballpark ranges of mpg, unloaded. Any of these above have got to be better than my '85 K30 which gets a lousy 5 mpg. The other thing to take in consideration is the '94 can be bought for literally cheaper than the crew or sub. Seems like these older '91 trucks hold their resale values pretty good, so, thats the other thing I'm weighing with my options. Spill the beans. What would you guys say? The '94 is here and ready to go whereas the '91 crew and sub will take time to search and find.
