I only have to lift up 36 inches to get in the back of the truck. I think the one we have will lift up to 40" as it's set up, but don't hold me to that.
Actually the Stabile Lift company has been fairly decent on getting back to us on a used Stabile Lift. No worse than most anyone else (LANCE!). We bought a truck camper with a Stabile Lift on it but we didn't have the saddles that go under the truck. We strapped the camper to the truck with thick ratchet straps and brought it home on a 3 hour drive thru a tornado warning area (and we saw a tornado).
Bought the saddle brackets that go under the truck. LOVE the Stabile Lift. Drove the truck 3000 miles/14 nights. Leveled the camper in the truck bed every night. Only took the camper out of the truck once on the trip.
Our camper was somewhat neglected. I don't think the Stabile Lift jacks had been greased in years. So I think I will have to pull all three jacks and take them apart to clean and grease them. Still. I LOVE THAT STABILE LIFT. Nifty little bugger.
