I will post this answer here so it can be part of the archive for anyone else that comes along.
That lift is a Braun Tri Fold built on a Quad Van 4wd conversion.
The real issue that comes into play when picking a wheelchair lift for a 4wd van is the distance between the ground and the inside of the vehicle floor.
Most non-commerical single post lifts are maxed at 32", beyond that and you have to go with a commerical grade dual post lift.
The current Sportsmobile West 4wd conversions using a 285/75/18 tire put the inside floor at 34.5"
Great for 4x4 use, bummer for lift selection.
So what are the options?
Lessen the floor to ground distance either by tires, vehicle lift or picking a lower conversion like Quad Van or Quigley or talking with Sportsmobile West about a lower hgt conversion (not sure if that is possible).
Well if a person can handle a curb or 2in bump/rise with their chair then they could use the Tri Fold or Clear View or other lift and just let it hang 2in above the ground...might be dangerous, might work fine, not sure how a mobility shop would feel about that
Custom floor cutout in the lift base area, any decent body shop might be able to make this happen or the mobility installer if they understand the idea, yeah you will end up with a funny looking interior floor with a dip in it of 2 inches but hey in the disabled world we are used to funny looking adaptive equipment.
I am sure there are solutions out there I have never seen or heard of, I am sure there are creative minds who are smarter than me and are working hard at making things better, and I can't wait to see what the future holds.
