What suspension changes for towing?

As other have already said, it's fine and leave it alone.

 

I'm sure you are right. I am probably over thinking it. The truck drives like a dream pulling the boat as is.

 

I have a 20' fishing boat with a similar weight. Never even considered adding any suspension aids.

 

My 18' Ranger is nowhere near the weight of the OP's boat but @Coachbuilder1 advised me that if you get any squat in the rear then the TSS system and traction control can get squirrelly.

 

Air bags. I had sumo springs but swapped them out for the custom control that air bags provide.

 

If you still have the Sumosprings I would buy them from you. I need them for my TT.

 

As you can see by the photo, I might get an inch of squat. There is NO traction control or TSS system issues whatsoever. I think I'm going to put this behind me and just enjoy my truck as it is. Thanks.

 

If you want, put air bags on it. They’re not that expensive, especially if you do NOT do the onboard compressor, etc. I had them for 2 boats of mine (24’ single diesel express sport fisher and a Malibu inboard ski boat). I was very happy with the Firestone bags. I routed the air fils to the bottom of my rear license plate holes. Super convenient and looked trick.

Anyway, my 2 cents if you go that route.
It was totally worth it for me.

 

Thanks for the input buddy. I will sleep on it for a while. Might just leave it alone for a while. But I do like the adjustability of the air bags.

 

I am still evaluating the Roadmaster Active Suspension. I think your rig looks very level and I would go with it but, if you have concerns, I think you ought to look at that product....it does provide some lift when not loaded and provides some relief from squatting when loaded up. Not expensive and relatively easy to install. It's not as aggressive as a WDH but that is not what you are looking for...

 

Sorry, returned them for refund.
