Here we go. 04 trailblazer, 63,000 miles, 373 rear. I6 4wd, swb with external trans cooler. I bought this vehicle to tow my TT. TT is 18ft 3,600lbs dry, 350 tounge wieght, I have wieght dist hitch with sway bars and elec. brake contrl. Now my question is... the ass end hangs low under full weight of a trip when packed. I am at 4 links on the wgt dit/ sway hitch, when the book says 5 links.(never has been a prob) to help with the prob I think i could use new shocks. Quest 1) sears has a deal for free install on monroe sensatrack. Will that help to keep ass higher under tounge weight? and will it help ride at normal load? For free install is it worth it? Quest 2) Whatt else would you do to keep as a tow vehicle : Trans fluid cleaning? Rear diff seals? Front end suspennsion???? Trailblazer is used 20-30 times to trailer per year. From shores to mountains, in jersey and pa mostly. I have towed my tt for a year already and other than HORRIBLE gas mileage it works well. I belive I am towing on the higher end of its range but has been a great vehicle.
