Roads in the states are maintained on the regular and built to last. A lot of the roads south of the boarder are either not paved or not maintained very well, which leads to a bumpy ride. With this in consideration as well as all the extra weight we will be carrying in the truck, the stock suspension is going to fail. We went with the OME full suspension kit with Daker leaf springs. This might be over kill, but we thought it would be a good idea to have a high end suspension for the 30,000 mile overlanding trip. Now i just have to get it on the truck somehow.
