RV Weight Ratings Guide

Understanding GVWR, GCWR, and weight limits for RVs in Colorado. Critical for safety and compliance.

RV WEIGHT RATINGS EXPLAINED

KEY WEIGHT TERMS

GVWR (Gross Vehicle Weight Rating)
Maximum weight of a single vehicle including cargo, passengers, and fluids.
• Found on door sticker or certification label
• Set by manufacturer - never exceed this

GCWR (Gross Combined Weight Rating)
Maximum combined weight of tow vehicle + trailer.
• Found in owner's manual or tow guide
• Critical for travel trailer and fifth wheel setups

Pin Weight (Fifth Wheels)
Downward force on the hitch - typically 15-25% of trailer weight.
• Counts against truck's payload capacity
• Heavy pin weights can overload rear axle

TYPICAL WEIGHTS BY RV TYPE

| Type | Empty Weight | GVWR | Notes |
|------|--------------|------|-------|
| Class A | 13,000-30,000 lbs | Up to 40,000+ lbs | Many exceed 26,000 lb threshold |
| Class B | 6,000-8,000 lbs | 8,000-11,000 lbs | Always under CDL threshold |
| Class C | 8,000-12,000 lbs | 10,000-14,000 lbs | Most under threshold |

| Fifth Wheel | 7,000-16,000 lbs | 8,000-20,000 lbs | Check truck payload for pin |

FIFTH WHEEL + TRUCK COMBINATIONS

Example calculation for 15,000 lb fifth wheel:
• Pin weight (20%): 3,000 lbs → must fit in truck payload
• Truck GVWR: 10,000 lbs
• Truck + fifth wheel GCWR: ~25,000 lbs
• Result: Under 26,000 lb threshold - standard license OK

TRAVEL TRAILER COMBINATIONS

Example calculation for 8,000 lb travel trailer:
• Tongue weight (10-15%): 800-1,200 lbs → counts against truck payload
• Truck GVWR: 7,000 lbs
• Combined GCWR: ~15,000 lbs
• Result: Under threshold - standard license OK

SAFETY STATISTICS
57% of RVs on the road exceed at least one weight rating. Get weighed!

WHERE TO WEIGH YOUR RV
