Considering an 18bx for a basement and I really would benefit from it being mobile.. I have 8' ceilings but have HVAC in some spots at 79".

Spec for the 18bx says 77.75". Any one have one with the stock mobility kit that can measure it's maximum height ?

Any comments on how tippy it seems when moving it around ? My floor is poured concrete with ~1/4" grooves every 36" or 48" in a grid pattern. I move a fs41 over it mostly fine, but it's not ever going to fall over.

Thanks,
Mark
