For a second wheelchair I was thinking of a cheep/free adult hospital grade wheelchair that you could just leave outside an push her around in so you would not have to carry her.Thanks, Rebel, for the quick response! We had no end of trouble just getting the gait trainer covered - the insurance company felt that they'd paid for her wheelchair so they'd covered her mobility needs and weren't covering the gait trainer. They denied us both on the first application and then on appeal. (Her first baby chair was a loaner from Children's). So I doubt very seriously if we could afford a second chair. And that still wouldn't solve the problem of her hands touching the wheels - they don't make pediatric wheelchairs with the outer push wheel because children's arms aren't long enough to extend out that far. So whether it's her present chair or a second chair that issue would still exist. With her small size she has to be fitted to her wheelchair and have it built for her. They explained to us that that's critical because of tethering in her back.
I could look into the Powerwheels jeep, though. Is that the one that is found in the toy stores or is it an actual pediatric medical mobility device? If it's like the one I'm thinking about, that is operated with her hands. I'm afraid I'm coming across as a little dense, but this is all new to us yet and we just learn as we go along.
Yep, powerwheels are toys you can get at walmart or on craigslist.
I would look for something like this. https://sandiego.craigslist.org/csd/tag/4533205599.html

These dont have sides so she may be able to learn to get in an out on her own from her chair. It also has a bed so you could put tools, buckets an feed in it for her to hall so she feels like she is actually helping. They also have seetbelts.
You can also mod these things. My brother studded the tires on the one he has by screwing self taping screws in them. Took 5 minutes an made it pretty aggressive in his rough yard.
Youtube is full of people modding these.
This guy is making one solar. He also shows that an adult can ride these.

This guy is upgrading tires.

Then there is extreme barbie jeep racing...
