Suspension upgrade for hauling question

I own a 2006 DC 4x4 TRD Sport non TSB

All of my driving is on pavement, but I am going to be purchasing a RV this spring and was wondering what "improvements" do you suggest I make to the suspension. I want to keep the ride "comfortable" and stable and also be able to handle a 6,000 lbs. RV.

Thanks.

 

u may want to get an AAL put in or put in a set of Air bags to maintain a decent ride height and not have it squat so bad. also ive heard of people puttin in Timbren bumpstops when hauling alot to prevent bottoming out.

 

How much would AAL add in height? How would they affect the ride quality? Would I then need to get a set of 5100's and adjust them to make the truck sit even? If so, how much adjustment would it probably require and can you adjust after install?

Thanks.

 

Peronally, I wouldn't go with an AAL. If you're hauling regularly, that AAL is gonna sag or break eventually.

Do some research on aftermarket replacement leaf paks, helpers springs, & airbags.
