I don't know if Ray ever got the ramps, but I did try a set that a neighbor had in their garage that was very similar, and I have to say that I would go with the F&G "elevator" all day, every day over those dang ramps!
I had a hard time wrangling them around - I was in constant fear I would drop one on my foot, or pinch my fingers in the mechanism somehow (if it can be done, I will do it! LOL)
They just felt... unwieldy to me, if that makes sense.
The thing I like about F&G's "elevator" device (in addition to it's light weight) is that I can move it from car to car and no installation or special wiring is needed.
I don't have to worry about having someone along with me who can lift Figgy into and out of my car if I can't do it.
I don't have to worry about (potentially) tearing up my bumper, the rear seal on my back hatch, or Figgy sliding him up and over and into the car, or down and out of the car; so it protects my car, *and* my chair.
I know it's super spendy compared to a pair of ramps, but for me it's probably the best and safest solution, especially for solo travel. My hubs won't be retiring for several more years, and our (adult) daughter will (eventually) be moving for her job to California (although not until after July 1st now).
Because it's part of my F&G, I could put it in a suitcase or duffel by itself, or with other medical equipment/supplies, and it would fly for free on US airlines - allowing me to rent a "regular" SUV at any destination.
That's my thoughts on it - I know that you asked our friend
@RaySharpton, and hopefully he will be along soon to share his insights!
