The Buick GL8 was one of the earliest carriers of the "bed vehicle culture" in China — second and third row seats folded down + floor installation = a temporary bed space of 1.8×1.4 meters. I have personally modified 30+ Buick GL8 bed vehicles, and today I'll give you a clear analysis of "whether it's worth installing."
▲ GL8 Camping Floor Modification as a Bed Vehicle: Real Modification Results
1. The 3 Truths About GL8 Bed Vehicle Modifications
Truth 1: The original floor cannot be used directly as a bed
The 3 problems with the original carpeted floor:
- Uneven surface: The carpet has wrinkles, making it lumpy to sleep on
- Not waterproof: Camping may encounter rain, and the carpet absorbs water and gets moldy
- No insulation: In winter, directly touching the carpeted floor is too cold to sleep
Truth 2: A modified floor doesn't equal a "comfortable bed"
After modifying the floor, flatness + waterproofing + insulation— all three core issues are solved. But to turn it into a "comfortable bed," you also need:
- Mattress (5–10cm thickness)
- Bedding cover (stain-resistant, easy to clean)
- Ventilation (leave the window slightly open at night)
Truth 3: The modification approach affects long-term use
- HPL aviation aluminium floor: Wear-resistant, can sleep on directly
- Fabric-textured SPC: Lightweight, comfortable
- UV print: Fades in 3–5 years, not recommended
2. Comparison of 3 Modification Options
Option 1: HPL aviation aluminium floor
- Price: 5000–8000 RMB
- Wear resistance: 8000–15000 revolutions
- Can sleep on directly: Yes (smooth surface)
- Insulation: Medium (solved with a mattress)
- Suitable scenarios: Long-term bed vehicle + business reception dual use
Owner feedback: "A bit more expensive but durable, slept on it for 1 years with no issues"
Option 2: Fabric-textured SPC
- Price: 6000–8000 RMB
- Weight: Lightweight (density 0.8g/cm³)
- Can sleep on directly: Yes
- Insulation: Good (fabric fiber structure)
- Suitable scenarios: Pure home-use bed vehicle + occasional camping
Owner feedback: "Most comfortable to sleep on, but not as wear-resistant as HPL"
Option 3: UV print
- Price: 2000–4000 RMB
- Wear resistance: 2000–3000 revolutions
- Can sleep on directly: Barely (fades in 3–5 years)
- Insulation: Medium
- Suitable scenarios: Short-term trial
Owner feedback: "Cheap but not durable, regretted it within half a year"
3. 3 Core Points of GL8 Bed Vehicle Modification
Point 1: Flatness of the second and third rows
GL8 Luzun / Pangtouyu—after the second and third rows are folded down, there is a height difference of 5–8cm, requiring:
- Leveling treatment during modification (raise or lower)
- Otherwise you'll tilt to one side when sleeping
Point 2: Modular design
Bed vehicle scenarios have high modular requirements:
- Daytime requires business reception (third row seats in normal position)
- Nighttime requires camping (second and third rows folded down into a bed)
- Modular design makes both scenarios usable
Point 3: Power supply reservation
Camping scenarios require power (phone charging, portable fridge, lighting):
- Reserve 220V power outlets during modification
- Or install an inverter (12V → 220V)
- Wiring should be concealed so it doesn't affect sleep
4. 3 Real Owner Cases
Case 1: Mr. Zhou from Shanghai (weekend camping)
Modification plan: HPL aviation aluminium floor Used for 1 years: Camping 1–2 times per week Original quote: "HPL is wear-resistant, bed vehicle + business reception both work great"
Case 2: Ms. Li from Chengdu (long-distance self-driving)
Modification plan: Fabric-textured SPC Used for 1 years: Long-distance self-driving 5–6 times per year Original quote: "Fabric texture feels great to sleep on, most comfortable for long trips"
Case 3: Ms. Wang from Hangzhou (short-term trial)
Modification plan: UV print (initial) Used for 6 months: Fading + seams widening Second modification: Changed to HPL Lesson learned: "Don't go cheap for short-term trials"
5. 3 Criteria for Judging Whether It's Worth Installing
Criterion 1: Frequency of use
- 1+ times per week: Worth installing (recommended HPL or fabric-textured)
- 1–2 times per month: Optional (recommended mid-range HPL)
- Occasionally 1 times: Not recommended (just use the original carpet + sleeping bag)
Criterion 2: Usage scenario
- Pure camping: Fabric-textured SPC (comfortable to sleep on)
- Camping + business reception: HPL process (durable + multi-scenario)
- Occasional camping: Mid-range HPL (high cost-performance)
Criterion 3: Budget
- Budget 5000–8000 RMB: HPL process or fabric-textured SPC
- Budget 8000–12000 RMB: High-end HPL + mattress
- Budget 12000+ RMB: Yunluo pure aluminum + high-end mattress
6. 3 Core Recommendations for GL8 Bed Vehicle Modification
Recommendation 1: HPL process is the best value solution
HPL process + modular design balances durability + business + bed vehicle use, and is the optimal solution for GL8 bed vehicle modification.
Recommendation 2: Must install power outlets
Camping requires installing 220V power outlets or an inverter, otherwise you won't be able to charge your phone, use the fridge, or lighting.
Recommendation 3: Add a 5–10cm mattress
Modified floor ≠ comfortable bed; you need a mattress 5–10cm thick to sleep comfortably.
Feedback from GL8 Bed Vehicle Owners I've Seen
I have personally modified 30+ Buick GL8 bed vehicles. Here are some common owner feedbacks:
- Mr. Zhou from Shanghai: HPL process modification for 1 years, camping 1–2 times per week, wear resistance is like new
- Ms. Li from Chengdu: Fabric-textured SPC modification for 1 years, best sleep feel for long-distance self-driving
- Ms. Wang from Hangzhou: UV print modification for 6 months, forced to do a second modification after fading
Last year, a modification shop owner told me: 80% of bed vehicle modification owners ultimately chose the HPL process—durability + dual-use for business reception are the core needs.
7. Frequently Asked Questions (FAQ)
Q1: Is it worth modifying the GL8 floor as a bed vehicle? A: Yes, provided you choose HPL process + modular design.
Q2: HPL or fabric-textured? A: HPL is wear-resistant and durable, fabric-textured feels better to sleep on. Choose based on your usage scenario.
Q3: Do I need a mattress after modification? A: A mattress 5–10cm thick is recommended; sleeping directly on the floor is not comfortable.
Q4: Do I need to add power for camping? A: Yes, otherwise you won't be able to charge your phone, use the fridge, or lighting.
Q5: How long can a GL8 bed vehicle last? A: HPL process 10+ years, UV process 3–5 years.
Q6: What's a reasonable modification budget? A: 6000–10000 RMB is recommended (including mattress).
