If you're talking power chair and a power lift, it will probably come close to or exceed the weight rating for the hitch. And that's assuming you can find a lift to fit the 1-1/4" hitch opening. I definitely would not consider one of those 1-1/4 to 2" adaptors. If memory serves, the tongue weight limit is 200#.I just bought a used Kia Soul 2012 and want to find out if a wheelchair lift can be used on it. The lift we have attaches to a trailer hitch.
Consider a portable lightweight wheelchair if it's within your say so. My relative has an Electra7. It's only 50lbs. I can pick it up and load it into the back of my Soul. She has a Tuscon and a pair of aluminum ramps and we can roll it in or out of the back. I haven't tried the ramps on my molten.I just got a 2020 Soul my wife is disabled. She's getting a power wheelchair. The chair is 225 lbs plus whatever the carrier weighs. The hitch receiver is 1 and 1/4 weight capacity is 200 lbs so I don't think I can do it
