Hello, I am new to this forum and I'm looking for some knowledge from people that are more familiar with OBS GM vehicles than I am. I'm in the market for a new daily driver and I think it would be fun to get an off road capable vehicle that I could take camping in the Sierras. I really like the OBS 4 door Tahoes and I would get one and put a ~3 inch lift on it with some 33x10.5 tires. While this would be a fun car off road and fit my camping desires I am concerned that the gas mileage would be too bad to deal with as a daily driver. What gas mileage would I get with a set up like this? Whats the minimum I would have to lift the Tahoe to fit 33s without any major trimming? What suspension lifts would you suggest? Would re-gearing the diffs be essential with 33s? Thanks!
