I now have two trips with the new 86fb and all I had added were timbrens knowing that I may have to add something extra after several trips. They were actually doing great until the last trip and launching the boat. my son usually just backs up and puts me in the water but since this was the first time with the 86 I was on the ramp to guide if needed. as the boat was going down the ramp I happen to look down and the spare was only about 3 or 4 inches from hitting the ramp...not good. I know super springs worked great on the old truck and camper as they kept it from dropping to low, so if launching a boat or backing down a slop you might think about the super springs. I usually don't drive at night so I don't worry about the lights but they should help there also as the rear doesn't drop as low.
