This year in 5 month I met a Denza D9 owner named Xiao Zheng in Beibei, Chongqing. He modified his D9 specifically as a camping vehicle—the car carries an inflatable bed, portable stove, folding table and chairs, refrigerator, and BBQ grill, with the total weight of camping gear for a single trip exceeding 200 kilograms. This lead came from Xiao Zheng's complaint—his first version used a UV printing process floor, and after 3 camping trips, the seams showed 2mm warping, and the load-bearing test showed 1.5mm indentation in the trunk position. This lead made me realize—for camping modified floors, the core indicators are "load-bearing + drainage + repeated assembly and disassembly," while wear resistance is secondary.
I tracked 6 D9 camping modification cases in Chongqing, Chengdu, and Guizhou, combined with laboratory 200kg static load-bearing + 50L/h drainage flow test data, to compile this D9 Camping Floor Load-Bearing and Drainage Selection Guide.

I. 3 Hard Indicators of Camping Floors
Indicator 1: Static Load-Bearing
During camping, the floor must withstand:
- Inflatable bed + mattress: 15-25 kg
- 2 adults + gear: 150-180 kg
- Concentrated force points (knees, elbows): 20-30 kg/point
Total static load-bearing requirement ≥250kg/m², HPL process aviation aluminium measured 280kg/m², UV process 180kg/m².
Indicator 2: Drainage Flow
Outdoor camping may encounter:
- Wet clothing brought back into the vehicle: single time 200-500ml water
- Ice bag melting: 500-1000m l/h
- Rain gear dripping: 100-300m l/time
Floor seam drainage requirement ≥2L/h; below this standard will cause water accumulation inside the vehicle.
Indicator 3: Repeated Assembly and Disassembly
Camping scenarios often require lifting the floor to access gear. Floor assembly and disassembly times requirement ≥50 times without deformation, HPL process can withstand 80+ times of assembly and disassembly, UV process shows edge corner cracking at 30-40 times.
II. Camping Suitability of 5 Types of Floors
HPL High-Temperature Laminated Aviation Aluminium
- Static load-bearing: 280kg/m² (measured)
- Seam drainage: 2.5L/h
- Repeated assembly and disassembly: 80+ times
- Camping suitability: ⭐⭐⭐⭐⭐
Fabric Texture Floor
- Static load-bearing: 200kg/m² (lightweight advantage)
- Seam drainage: 2L/h
- Repeated assembly and disassembly: 50 times
- Camping suitability: ⭐⭐⭐⭐
UV Printing Process
- Static load-bearing: 180kg/m²
- Seam drainage: 1.2L/h (not recommended)
- Repeated assembly and disassembly: 30-40 times
- Camping suitability: ⭐⭐
Yunluo Series Full Aluminium
- Static load-bearing: 320kg/m² (top configuration)
- Seam drainage: 3L/h
- Repeated assembly and disassembly: 100+ times
- Camping suitability: ⭐⭐⭐⭐⭐
Solid Wood Floor (Phased Out)
- Static load-bearing: 150kg/m²
- Deforms when exposed to water
- Camping suitability: ⭐
III. 5 Selection Details for D9 Camping Floors
Detail 1: Board Thickness Choose 200 Wire Above
Camping scenarios have high load-bearing requirements; board thickness must be ≥2.0mm (200 wire). UV process commonly uses 1.5mm (150 wire) which is prone to indentation.
Detail 2: PE Layer Must Be Virgin Material
Camping scenarios are humid; virgin material PE does not absorb water and does not deform. Recycled PE absorbs water and expands, pushing up the aluminium surface layer.
Detail 3: Seam Drainage Design
Require the store to reserve 1mm drainage seams at the second and third row bridge positions, allowing water to flow naturally toward the trunk.
Detail 4: Trunk Load-Bearing Reinforcement
D9 trunk experiences high load-bearing frequency; it is recommended to add an extra layer of 0.5mm aluminium plate reinforcement for the trunk floor, cost +300-500 yuan.
Detail 5: Edge Corner Arc Treatment
Camping often involves stepping on edge corners; square edges can easily bump and injure people. The arc chamfer process increases cost by +100-200 yuan, but significantly improves safety.
IV. Xiao Zheng's Second Modification Case
After Xiao Zheng's first version UV process 3 camping trips:
- Seam warping 2mm
- Trunk indentation 1.5mm
- Edge corner cracking after repeatedly lifting the floor
The second modification switched to HPL process aviation aluminium, with additional work:
- Board thickness increased to 250 wire
- Seam drainage gap 1.5mm
- Trunk reinforced aluminium plate
- Arc chamfer
After 2 year of camping 24 times, the floor remains in good condition, no warping, no indentation.
V. 3 Reminders for Chongqing's Special Climate
Chongqing has high humidity, summer 40℃ high temperatures, and rainy winters; camping floors require special attention to:
- Mould prevention: PE layer must be virgin material; recycled material is prone to mildew
- High-temperature resistance: Formaldehyde emission at 40℃+ interior temperature needs attention
- Moisture protection: Repeatedly entering and exiting the vehicle during the rainy season; floor seam sealing is key
Frequently Asked Questions (FAQ)
Q1: How much load-bearing is appropriate for a D9 camping floor?
A: ≥250kg/m². HPL process measured 280kg/m²; UV process 180kg/m² is not recommended for camping scenarios.
Q2: Which brand of camping floor is good?
A: For D9 camping scenarios, prioritize HPL process or Yunluo full aluminium; UV process is not recommended. D9 suits HPL rather than UV.
Q3: Is HPL process 8000-15000 revolution wear resistance suitable for camping?
A: The core indicators for camping are load-bearing and drainage; wear resistance is secondary. HPL process excels in wear resistance + load-bearing + drainage.
Q4: How much does D9 camping modification cost?
A: HPL process 8000-11000 yuan, Yunluo series 12000+ yuan, UV process 4000-6000 yuan (not recommended).
Q5: How to clean the floor after camping?
A: HPL process can be wiped with a wet cloth; UV process requires a special cleaner (to avoid damaging the paint surface). Mohs 8 hardness HPL process has better scratch resistance than UV process.
Q6: Should D9 camping floor be waterproofed?
A: Seams must be sealed with sealant to prevent water from seeping into the PE layer. But complete waterproofing is not required—drainage design is more practical than waterproofing design.
