Problem with chucking need answers

[Tile Guy]

I have a 2009 MS 32TK3 and I am pulling it with a 2016 Dodge 3500 SWD long bed. I have just recently raised the MS 2.5 " due to the truck being higher and the 5th wheel being low in the back. I also upgraded the wheels and tires to Sailum 17.5". I have my hitch down as low as I could that left me with about 5" above the bed rails. I lifted the trailer by installing the Correct Track system and Lippert said I could not use the Centerpoint air ride system so I got the Equa Flex system. Took it out for a test drive and really bucked and rode terrible. I called Lippert and asked them why I am not able to use the Centerpoint system and they ended up checking with there engineering and they said it would be ok to use the CenterPoint again. I had a hard time understanding why I couldn't use a $1600 Centerpoint system and have to use a $300 Equa Flex system. So I was just out of 2 days of working on it and $300. + bushings and bolts...UGH. Well it still has a fair bit of chucking issues. The truck squats a lot so I am thinking of airbags on the truck. Not sure if this is the trick or not. Any ideas
