I had the HWH Kick-Down Levelers installed. I love em. All I have to do is jump out, put some pads below the levelers to spread the weight, jump back in and press a button. Viola!
Don't have that model, but I had auto levelers on my seriously wanted list. The MH we landed in didn't have them, so i have been planning to add them aftermarket...
but honestly so far have only needed them maybe less than a handful of times, so it's hard to justify spending that kind of money and the hit on weight, compared with the few pieces of scrap lumber I tote around
I think it depends on the places you go
