There is another lift option that I seldom hear anyone talking about. That is a 22 1/2 degree lift. Its half way between (about) no lift and the high lift option. My 17A looks to my eye, with the high lift option, as too high. Wish I had opted for the 22 1/2 degree lift. Same cost. It adds about 1.5 " of lift..... the full high lift adds about 2.5" Now with that said .... I haven't owned my trailer long enough for it to have a "full load" with all the acuminated stuff and water that one seems to gather. I may have another thought then.
I can't help it ...... I grew up reading Popular Mechanics in the 50's and 60's .....
