Power lift for RV

My wife is an amputee and I installed a Burr Handi Lift for her to use on our travel trailer. It is not compatible with a wheel chair. The basic model is a stand on only. Burr did start offering a seat option for what I consider to be a ridiculous $600.00 upcharge. Shop around and you can get the basic lift for about $1300.00. Make sure that it has enough travel to reach the ground. I think 45" is the standard lift but it can be increased. I had it installed at my RV dealer, that ran about $600.00. It was worth it. The only complaint my wife has is that she would like for it to raise up faster. It takes almost two minutes to come up 3 feet.
