gear ratio ?

[krazy_texan]

ok guys here is the deal i have my 1990 suburban i have been driving for sometime now. it had 3.73 gears in the rear but the ring gear broke a few teeth so i had a set of 2.73 axles laying around i through the rear one in my truck to get me back on the road and now i am hating my fuel mileage it is far worse than it was with the 3.73. i have since acquired a set of 12bolt 3.08 axles and now i am at a toss up with what to do. should i throw the 3.08s in the truck and drive it or should i spend the money rebuilding and re gearing the 3.08s to either a 3.73 or 4.10. just so you guys know that my plans within the next year are to remove the 3 in lift in the truck and go with a 6 in lift and 35in tires and i want to be able to pull a 20ft camper or my car hauler with ease. so what should i do gear wise with my truck. what are you guys running in your trucks.
