Off-road camper trailers are a very suitable tool for outdoor adventures and travel, which can provide enthusiasts with more freedom and convenience. Not only can they travel in different natural environments, but they can also provide comfortable accommodation space and basic living facilities, allowing travelers to feel at home wherever they are. Whether crossing rugged mountains, crossing the vast Gobi Desert, or traveling through snow and forests, the versatility and adaptability of off-road trailers make them an ideal choice for outdoor enthusiasts.



Off-road camper trailers require a rugged, durable structure that can withstand challenging environments such as rocky trails, muddy paths, or extreme weather conditions. The materials used must be corrosion-resistant and shock-absorbing to protect the trailer’s interior facilities and occupants. TOPOLOGROUP provides reliable box construction solutions to off-road trailer manufacturers. These solutions address a variety of frequently faced structural issues, ensuring that each trailer is designed for maximum durability and performance in the harshest environments.



Modular structure & quick assembly
Each part of the off-road camper trailer body is manufactured separately in our factory. After receiving the box in CKD, SKD or CBU form, they can be quickly installed on the chassis with simple tools (electric drill, hammer, glue gun, etc.). Due to the simplicity of operation, only a few people are needed to assemble a trailer.

Lightweight & High Strength & Thermal Insulation
The body panels of the off-road camper trailer are new fiberglass composite panels that combine different materials to optimize the structure and performance. It achieves many advantages such as thermal insulation, waterproof and moisture-proof, durable, and aesthetic display.

Outer Skin
- The outer skin is made of high-gloss thermosetting FRP (fiber reinforced plastic) sheet, which has a series of unique advantages, making the off-road trailer not only excellent in function, but also more beautiful in appearance. Its surface is flat and smooth, which can effectively resist the adhesion of stains and water stains, and is easy to clean. Users can easily wipe off surface impurities to keep the appearance clean and new.
- In addition, the surface color can be customized according to user preferences. This customized design allows each off-road trailer to be personalized according to personal preferences to meet the needs of different users for appearance style.
- This thermosetting FRP sheet also performs well in weather resistance and UV resistance. It will not fade or age when exposed to outdoor environments for a long time, ensuring that the trailer’s appearance always maintains bright colors and textures.
Embedded Frame
- Aluminum alloy pipes are used as the structural frame, and waterproof plywood is laid on the edges of the reserved positions for doors and windows to enhance the nail holding force for easy installation.
Core Material
- The core material is closed-cell XPS (extruded polystyrene) foam, a material with excellent thermal insulation properties that is widely used in high-performance insulation systems, especially in environments that need to withstand extreme temperature differences. The closed-cell structure of XPS foam means that it can effectively prevent water vapor exchange, thereby preventing moisture from entering the interior and exterior of the trailer, preventing mold or structural corrosion caused by moisture accumulation.
Energy-absorbing Layer
- The energy-absorbing layer is made of LWRT (lightweight reinforced thermoplastic) material with high shock absorption performance. Its addition greatly improves the strength of the trailer panel, can effectively absorb external impact force, and reduce damage to the trailer.
Inner skin
- It is a new type of thermoplastic FRP sheet (CFRT – continuous fiber reinforced thermoplastic), which has extremely high compressive and tensile strength, providing the last barrier for the safety of the interior of the trailer.
