We to faced that dilemma when we started looking at upgrading from our pop up. Besides what others mentioned about advantageous of Truck Campers I would note that the ability to separate the two unites allows:
- You have the use of a truck. We keep our camper on most of the time but once in a while we want to haul something and it sure is nice.
- easy service of either unit. The truck at truck places and the camper at RV dealers
- The ability to upgrade either unit separately or to switch to something else. For example, maybe down the road we will want to switch to a 5th wheel. Easy to do in our case.
Other things we might note:
- As others have noted, ground clearance is a big deal.
- Tank capacity. Many of the C's with the same length are pretty limited.
- Crew cab seating capacity. Yes, you can sit more people in the "body" of the C but safety is limited.
Your choice may be different but we spent amounts in your range to get our truck and camper and we couldn't be happier.
