Good advice, go out and find out where it falls short for yourself, what suits you may not suit me. I have managed to get through to 200,000+ on standard suspension on all surfaces without too much trouble. Have just done a 2"+ lift with Zordo, very pleased with the outcome.Just get out there in it first and find out what you think you need. They are very capable stock with just decent tyres.
the children here will have you blowing $500k before you hit the dirt.
FWIW 4inch lift and 33's would look like a 1970's rollerskate.
