Getting codes on cylinders 1, 3, 5 and 6. Anything I should be worried about. Truck has almost 130k on it. PIP tuned, not sure what version and full weight loss.
Not many options with the flow through. I have a console vault, so that is out. Thought about under the seat, but then an external speaker would be needed.
I use the torklift brand. My camper weighs a little over 4k. Without the stableloads, the truck would drop 4+ inches. With them in place, it'll drop about an inch. Shocks are on the list for replacement. Haven't made up my mind if I want to replace the sway bars though.
The torklift system is rated for his situation. http://www.torklift.com/index.php/products/towing/superhitch-everest-wd-system
I agree with the trailer issue. If it's frame induced sway, no WD will fix that.
