Our 3023 has the lift kit and am glad that it does. Our driveway is very steep. Without the lift, the jacks would hit preventing us from bringing the rv into the driveway near the house. Also, with the overhang of the unit behind the wheels, I feel more confident that we will not hit on any of the entries into gas stations and other areas that may have steep pavement that quickly transitions to level ground. There was one recent post of a unit without the lift hitting in a gas station pulling the scissor jack off of the rear of the unit.

Concerning the stair height, we do not notice any inconvenience in stepping up the two steps into the Trailmanor.
