mckenzie... too much gas will hurt you because youll break the tires loose then lose all your traction so depending on how steep it was... get a bit of a run at it and hit about 4low 2nd gear so you have good momentum and just dont let out of it... as far as sliding down backwards... jam it in reverse as best and quickly as you can and use the gas to steer it back and forth... ill show you sometime... and get some goodyear mt/rs
