I have a 98 XLT with 16" wheels SOHC. I just bought a camper that has a hitch weight of around 500lbs (maximum recommended for the explorer). The back of the truck rides lower than I like and I am wondering if I can have some kind of heavy duty springs or shocks put in the back. I am not neccessilly interested in lifting the truck just giving it a stronger back end to tow the camper. I don't wish to jeopordize the ride as its my wifes vehicle. I also dont want to spend more than a few hundred dollars. Can anyone suggest anything to me?
