Thru the years I have owned 4 truck campers before moving into a 5th wheel when I retired. Now on my third 5th wheel but would go back to a truck camper in a heartbeat if the wife would agree!! Apparently when a woman experiences counter space and closet space she is reluctant to give it up. Truck campers are easy for many reasons. You don't have to do much planning with a truck camper. Any state or national park can accommodate you and there is no issue with length ! Many parks were constructed before people traveled with long tall trailers. Generally I've found most private parks will find somewhere to put you up for a night. Not so with a 5th wheel. Traveling on narrow roads is no issue with a truck camper. Switchbacks and steep curvy roads are not a problem. Pulling a boat trailer or horse trailer is no issue. I generally plan weeks ahead of a trip with my 5th wheel. I research routes, road conditions, campground availability and all other aspects of traveling with a big rig. We are reluctant to travel the back roads for fear of getting trapped. Scenic pull offs are a big concern for fear of not being able to get in a out easily. Thus we have missed some beautiful views in our travels. Buying fuel is a major concern with a 5th wheel. Most stations now have the pump lanes facing the building instead of being parallel to it. This can cause major issues trying to get in and out in a limited space! No problem with a truck camper. Basically you drive like you do without the camper onboard or with a car. Of course there is a downside to a truck camper. Limited space is the number one issue for my wife but I like the ability to go anywhere without considering any restrictions except possibly height. Truck campers in my opinion are profanely expensive considering they are much smaller, have no axle or frame or brakes and must be easier to build. Yet they cost as much as a 5th wheel !! If you have a dually already you have the ability to carry a good size truck camper with no problem. It's all about how you travel and how much pre planning you want to do. We have changed to reserving a campsite for a few nights in an area we want to visit, dropping off the 5th wheel, then driving around for a few days site seeing the area. It works well in a place like Grand Tetons or Glacier National Park where you can spend several days in one area and be entertained. I'm very cautious about getting into an area I'm not familiar with while pulling the 5th wheel. The truck campers we've owned were not a concern. You can be spontaneous in your travels and exploring!!
