How to Make Sure Your Truck Can Safely Carry a Slide-In Camper

I have traveled extensively throughout the US for many years and enjoy helping people to make the most of their RV vacations.

How Heavy of a Camper Can I Put on My Truck?

If you are thinking of purchasing a slide-in camper, you need to make sure the one you buy is not too heavy for the truck that will carry it. To do otherwise can endanger your safety when you are on the road, and while it may appear that all campers are more or less the same, this is not true.

Dry weights can vary by thousands of pounds depending on brand, construction, amenities and add-ons, and if your truck is not properly weight rated for the unit it will be carrying, you are asking for trouble.

It's important to match your pickup truck to the camper that will be loaded onto it.

Camper Weights Vary

If you already own a pickup truck and want to buy a camper for it, its size, bed length, number of tires, type of tires and weight rating will determine the type of camper that will be safe to use.

Since some slide-ins have dry weights as high as 3,900 pounds, you cannot expect a half-ton truck to be able to carry one of them safely, and you certainly will not be able to load one onto a truck with a short bed.

However, if you don’t own any equipment yet, you have much greater leeway when it comes to the type of truck and camper you may purchase.

The trick is to do plenty of research before you make your decision.

Do You Need a Dually?

Opinions vary about whether you need a pickup with dual rear wheels when you use a camper. Vehicles like these are more expensive to own than standard pickup trucks and can be problematic due to their large size.

For example, if you live in a condo, you may not be able to keep a dually on the grounds, because unlike an ordinary pickup, it can't meet their definition of an "automobile"—a vehicle that weighs less than 6,000 pounds, has four wheels, and has no commercial signs on it.

Therefore owners may have to keep duallys in storage facilities along with their campers. This is both inconvenient and costly to do.

But the truth is that if you plan to purchase a heavy camper loaded with amenities, the only way you can carry one safely is if you drive a dually. Once you view the attached video, you'll understand why this is important to do.

Some people disagree with this thinking, but it is important to remember that campers are top-heavy, and the larger ones put extra strain on tires. The last thing you want is a blow-out caused by overloading your truck!

Dual rear tires can safely support more weight than singletons and thus are safer to use for carrying heavier campers.

Amenities That Can Cause Problems

It is important to remember that the more things you add to your coach, the heavier it becomes and the less safe it can be to drive. Furthermore, manufacturers tend to underestimate the weights of their units, so you would be smart to add an extra 10–20% to the total weights they provide.

Also, not all manufacturers include the same items in their “dry weight” estimates, but many add items to the basic stated weights, so you need to read the stats carefully before you decide to add extras such as generators and other types of equipment.

When estimating weights, you need to know some basics such as the weights of these items:

  • One Gallon of Water = 8.34 lbs
  • One Battery = 65 pounds
  • Personal Items = 500 pounds
  • One Slide Room = 400 pounds
  • Truck Diesel Engine = 600 pounds more than a gas engine

Always bear in mind that anything that adds weight to your travel unit is carried on those tires and that chassis!

Lightweight Options

Fortunately, if you are willing to make do with less, there are a few lightweight hard-sided campers with bathrooms on the market that can be safely used with standard half-ton pickup trucks.

They are manufactured by Lance, Northstar, Livin Lite, Alp, and Palomino, and you can read about them in this article from Truck Camper Adventure.

How to Decide

As stated earlier, if you already own a pickup, your decision will have to be based on its stats. If you don't, you may want to research campers, choose one you like, and then buy a truck that will be weight-rated for it. All manufacturers can supply you with the information you need in order to be able to do this, so be sure to get this information in writing before you make a final decision.

Unfortunately, few sellers offer both trucks and campers, so you’ll have to purchase them separately. For this reason, it’s best to buy locally, because once you buy the truck you can load the camper onto it, take it to a truck stop and weigh it on a certified scale.

Another good reason to buy both units locally and test-drive them is that if the center of gravity is not correct, you’ll have problems driving your unit.

Buying a Truck-Camper Combo Is Tricky

No matter what type of RV/tow vehicle combination you purchase, you have to make sure that your weight ratings are correct. However, because a camper is loaded onto the bed of a pickup truck rather than being a unit that is towed or tows, ratings become much more important.

Campers and trucks are the only vehicles that travel as one, so they are more dependent upon each other than other types of RVs.

As with all recreational vehicles, they have their pros and cons. They work well for some travelers, but not so much for others. Thus, before you decide to make a purchase, it might be a good idea to rent one and take a short trip to see how you like this form of transportation.

If you do decide that it is for you and as long as you take the time to do your research, you’ll be able to make sure that any truck you use will be rated to carry a camper of your choosing.

Good Luck.

Questions & Answers

Question: To get the exact payload capacity of your truck, do you add the front and rear axle weight limits, minus the wet weight of the truck camper? I really want a used truck camper, but don't have that or a truck yet, and want to really take my time and do all the homework first.

Answer: This is tricky because there are many variables. Before buying anything, research the size and type of camper you want to have. Then check with the manufacturer to get the correct weight. At the same time, get a hold of the manufacturer of the truck you think you want to buy to find out exactly how much of a payload it can carry. Generally speaking it's a good idea to buy a truck that has dual wheels on the back because anything you add to either unit will add weight and can change the dynamics. If you buy used, the seller can clarify what you need or may already be selling the truck and the camper jointly. However, even if this is the case you should check with the manufacturer of the truck to find out about weight distribution and carry capacity. I would also take some test drives in various units that are for sale to make sure you'll be able to handle them as they are bulky and can roll over easily.
