Don't know what to recommend on the 5th wheel but I can tell you this....keep the truck camper for those trips where you don't want to drag a big trailer around. We had 4 truck campers in a row and then on retirement decided to trade the truck camper for a 5th wheel. Oh boy was this a mistake!! We got nothing for it on a trade "because there is no demand for truck campers" and now we can't take the boat along and have to make two trips to get the boat. I have found that a truck camper allows you perfect freedom to go anywhere you want to go, park anywhere you want and have no threat of getting stuck in tight situations. Keep the truck camper and get the 5th wheel you want.
Also I have been looking for a decent used truck camper at a reasonable price but all the dealers want two prices for one "because it's a supply and demand type thing..few truck campers are available so the price is high." Try to figure this one out.
One type camper will not cover all situations. Keep the truck camper too!!
