I was concerned about tweaking the frame too but I don't think it is that much to do it. I measured the holes which are 1" apart so if you adjust the landing gear via the pins up or down the most it would be is 1/2 inch out. I will get the adjustable Ultra-Fab anyway so I can lose that unevenness. Probably only need it on one foot.
I stained and added rope handles to 4x6 blocks so I don't have to drop the gear that far, I use them front and back. I also take along two of the round ones in-case I ever setup in some mushy grass or sand.
