As a record collector I like the folding seats of my Chrysler Pacifica 2018. Unfortunately I can't use the available space to move as many heavy boxes of vinyl records as I want because the whole car sinks down and I drive on the side of the tires.

To increase the payload I am planning to do the following in one of these shops that convert Pacifica's for wheelchair transport:



1. Stronger spring coils (would Jeep Cherokee coils work since the car is built on the same platform?)

2. Two inch lift all around

3. Get 10 ply tires



Does anybody have experience with a similar project?

What do the experts on this board think about these ideas?

Thanks for your help!
