I just bought a Palisade AWD LTD. I wanted to remove the 3 rd row seats and add a interior power lift for my Wheel Chair (Quantum Edge 3.0 I Level (400 lbs). It needs a Tongue weight of 500 while the palisade tongue weight is not defined yet. I am having difficulty finding an installer of a lift in Dallas area. Does any body has experience in getting this done.
