Max Step Height Into a Skid or Wheelhouse ?

Hey Guys……….
I’ve decided after a few years of testing that the low ride height of my Soderbloom Aluma-Lite 8′ x 10′ (with a 2′ V) skid house is getting me stuck to often.  I’ve already done a fair amount of re-engineering some things to overcome the problem, but in then end my only option left is to raise it up to an acceptable level.  A couple details to know are that I do have the older ski style (not the newer box tube skis), and I pull it with a 600cc atv with tracks.  What does everyone feel is an acceptable maximum step height to raise it to?  What heights are already on all of your houses?  The current height of the floor is about 6 3/4″ above the ski bottoms.  

Raise it to any height you want and make a portable platform to place just outside the door when you are using your shelter. Then you would take two steps into the shelter, instead of one big one.

My fish house has an 18″ step height and I do just fine getting in and out.
