I have an 05 expy with independent suspension all the way around, my problem is, that when I hook my 16ft trailer to it, it bottoms out, even when trailer is empty. Is there an air suspension kit I can install to fix this issue ?

How old are the spring/shock assemblies on the rear now ? What kinda tongue weight is that trailer ? Normally the Expy woudn't even know it's back there. Can you move the axle up forward on the trailer to better distribute it's weight ? Try a pair of Rancho adjustables on the rear, set 'em the way you want it to ride.

I’d check the tougue weight. I pull 6-7k lbs weekly in my 05. With a dump trailer. Only time it bottoms out is when it’s loaded front heavy. It has 185k. I replaced all the struts and springs 10k ago when one rusted and broke. I got motorcraft replacements from rock auto.
