Thanks for details ... I need em... I actually did add a leaf on the Tacoma for safety sake but it was a rough ride when camper was not in (6 months).
You are right ... do it right (the second time) ...wish I had realized the stock springs were so weak. I assumed as the truck was rated at 3/4 ton (more than Tacoma) that it would be okay. HA. I will do what's necessary and it sounds like that will be deciding whether to replace the whole pack or add a leaf (Fleet is nearby and did the Taco). Shocks.... finding who makes them for such a new truck is an issue.
I went on the ColoradoFans website and quoted below is what I got back ... Need to learn me up some...Eiback?
"I've got virtually the same truck as you, a Canyon, long bed, DMax All Terrain, and recently completed our first extended tow of our 19' travel trailer. I posted in this thread about our previous Nissan Frontier, which needed more power, but handled extremely well when towing, and had the OME suspension changes. And in another thread, I recently posted about our 1500+ mile tow in the Canyon, commenting about the need to beef up the suspension for towing. Just last week, I installed Auto Spring's add-a-leaf to the back, and Eibach Pro Truck shocks at all four corners, with the front being ride height adjustable so I could level it after the added lift at the rear. The add-a-leafs, which I asked be made with the lowest lift possible, added just under 1.5" to the rear, so set my ride height adjustable Eibach front shocks to the 1.4" lift setting".
