Shocks and trailering

[wingnut2u]

Ok, I have read the threads about all of the recommended shocks. I am leaning towards the Rancho 9000 adjustables. But as you can see by the pic, I trailer a heavy boat that drags down the rear of my H2. I do not have the air suspension.

Will I sink even more when I replace the stock shocks with the Rancho's or is there a better shock to use.

Anti-Blingers please go easy on me.

Sorry about the quality of the pic as it is from my camera phone.
