Safe to have rear suspension lifted for clearance?

[blue_seeker_1]

I just purchased an 05 Jayco Greyhawk 31 ft. my driveway from the road to enter the driveway is steep, I'm not sure my rv will make the grade up. How safe is it to raise the rear suspension 5-6inches?

Not a problem at all, just beware with that much lift you may have to check the caster on the front axle afterwards.

That said, my brother's driveway is ~25%. His Forester 30-footer, with a short wheelbase and monster overhang, somehow makes his driveway!

Try it first. You might only need a couple 2x8's if anything
