How Thick Are Camper Walls?

Campers come in many types for travel. Some people want to drive on big roads and see nice views. Others like to camp near lakes and rivers to fish. Choosing the right camper starts with learning about how it is made.

One important part is how thick the walls are. Thicker walls keep heat better and last longer. They also affect how heavy the camper is to pull or drive. All of these things affect your camping trip.

This article looks at normal wall thickness for different kinds of campers. It also talks about what campers are made from. By the end, you will know what thickness works best for what you plan to do.

Camper Wall Materials

Camper Wall Materials

Before diving into thicknesses, it helps to overview common wall materials. Most campers feature a layered construction for maximum insulation with minimum weight. Here are the primary materials used:


  • Lightweight and easy to work with but a poor insulator on its own.
  • Often used as an outer skin with insulation packed inside and out.


Laminated Wood Panels

  • Sturdier than single panels and protects against moisture.
  • Interior wood bonded between moisture barrier layers.

The combination of aluminum, fiberglass, wood panels and engineered insulation ensures robust yet reasonably lightweight camper walls. Let’s take a closer look at thickness ranges for different camper categories.

Travel Trailer And Fifth Wheel Wall Thicknesses

As towable vehicles, travel trailers and fifth wheels aim to keep weight low for tow vehicles to easily manage. Wall thicknesses therefore average in the 1/2 to 3/4 inch range, with specifics varying some by floorplan and interior features. Here are some breakdowns:

  • Basic Models: Expect walls measuring 1/2 to 5/8 inches for lightweight construction.
  • Mid-Range Models: 3/8 to 3/4 inches, allowing for more durable materials and insulation upgrades.
  • Larger High-End Models: Closer to 3/4 to 1 inch thick provides improved thermal regulation on extended trips.
  • Expandables and Pop-Ups: On the thinner side at 3/8 to 1/2 inches for minimized packed profile.

So in summary, the majority of travel trailers and fifth wheels contain walls averaging right around the 3/4 inch mark. Anything below risks inadequate insulation while much above cuts into valuable cargo capacity.

Motorhome Wall Construction

Motorhome Wall Construction

As self-contained motorized RVs, motorhomes don’t face the same weight restrictions as towables. Walls therefore skew on the thicker side, generally measuring 3/4 inches and up. Let’s break it down:

  • Class A Diesels: Often utilize fiberglass or laminated wood panels around 1 inch thick.
  • Class A Gas: Similar thicknesses to diesel but may lean more to aluminum at around 3/4 inches.
  • Class B/C Camper Vans: Space comes at a premium, so expect thinner 3/8 to 1/2 inch walls.
  • Large 5th Wheel Toy Haulers: Even greater insulation called for, up to 1+ inches common.

Motorhomes can drive on the road without another car pulling. Their walls are usually thicker than walls on campers pulled by cars. Thicker walls make the inside of motorhomes stronger. They protect better than thinner walls on campers cars must pull down the road.

Additional Construction Considerations

A few additional points are worth touching on regarding specialized situations:

  • Roof sections may utilize an even thicker gauge, up to 1.5 inches at times, for withstanding weather elements.
  • Basement/garage areas have reinforced walls up to 1.25 inches to brace holding heavier equipment.
  • Articulated & expanding floor plans may use incrementally thinner walls (0.5-0.625 inches) where flexibility is paramount.
  • High altitude or extreme weather models tend towards maxing out thickness guidelines for unsurpassed insulation.

Most campers have walls the usual thickness. But some campers need special things. Their wall thickness may change a little. Where it changes helps with what they need. Talking to people who make campers helps choose the wall thickness that best fits how you will use your camper.

Sewer, Fresh Water And Electrical Systems

Sewer, Fresh Water And Electrical Systems

We must talk about what is inside the walls too. Pipes for water and bathrooms are in there. Wires for lights and power are too. The walls need space for these. Thicker walls give more space. This helps everything inside work well for a long time in your home on wheels. Factors like:

  • Adequate spacing between wall panels for system access and repair
  • Durable shielding and insulation wrapping pipes/wires from external impacts
  • Sufficientbuffering interior systems from temperature swings

All become heightened concerns the thinner the overall wall construction gets. Thicker wall profiles better secure long-term plumbing and electrical integrity critical for comfortable dry camping.


Can you drill into camper walls?

RV walls are made with thin wood pieces. There are metal or more wood behind it. Stuff to keep warm is between. If your RV has wood behind, you can put holes in it to hang things. It will stay strong. Use a finder to see where the wood is so you don’t miss.

Can you mount a TV on a camper wall?

Putting a flat TV in a RV is easy. Some people want to put the TV on the wall though. A RV wall holder can help. It saves room. It looks nicer. And it keeps the TV safer when the road is bumpy.

Can you use a normal TV in a campervan?

You may need a lock for the TV on the wall. Some take the TV down when driving. You don’t need a TV for cars in your motorhome. But a normal TV needs power from outside. Unless you have something that changes the power from the motorhome batteries to normal power. Then you can use a normal TV without outside power.

Final Thoughts

How Thick Are Camper Walls? We have explored how camper walls typically range from around 1/2 to 1 inch depending on vehicle category. Most travel trailers and fifth wheels fall in the robust 3/4 inch zone to balance weight and shelter needs. Motorhome walls skew thicker overall given their self-powered capabilities.

Always discuss your particular plans with manufacturers to confirm wall thicknesses appropriately suit anticipated climate exposures and value longevity over raw functional weight figures. With the right setup, camper walls happily hug you through many epic outdoor adventures ahead.
