One advantage of having a truck and fifth wheel is that you can upgrade just one part at a time. Truck have really been increasing in power and capacity over the last few years and the latest ones have become powerhouses. So much so that unless you're into the large DP, the fifth wheel/pick up combo is going to perform much better. Also safety wise, pick ups are crash tested along with the mfg's putting in airbags/impact protection safety devises. Google motorhome crashes....not a pretty sight. Also depending on what type of camping you do the 4x4 can come in handy. We love this one campground and it has grass sites next to a creek. It happened to be a very wet fall last year. While camping there, the sites were not completely soft but were mushy. I was able to back in and with the 4x4 on able to ease my way back into the site with no trouble. Next site over a motorhome pulls in and about sunk it to the axles. Ended up having a tractor pull him out and he had to camp in a site far from the creek.
