• Cross chains under tongue (forms cradle if tongue drops)
• Leave enough slack for turns, not enough to drag
• Attach to frame, not bumper or hitch

FIFTH WHEEL CONSIDERATIONS
• Pin weight typically 15-25% of trailer GVWR
• Ensure truck payload can handle pin weight
• Many states require brake controllers for all fifth wheels
• Consider weight distribution for proper braking

TRAVEL TRAILER CONSIDERATIONS
• Tongue weight should be 10-15% of trailer GVWR

PRE-TRIP CHECKLIST
☐ Check tire pressure (trailer and tow vehicle)
☐ Test trailer lights and brakes
☐ Verify safety chains are crossed and secured

Propane/Tunnel - No Major Restrictions

No major tunnel restrictions identified in Montana. Always check signage before tunnels.

PROPANE AND TUNNEL RESTRICTIONS

WHY THIS MATTERS
Many tunnels prohibit vehicles carrying propane (LP gas) due to explosion risk in enclosed spaces. RVs with propane tanks must take alternate routes.

MONTANA RESTRICTIONS
No major propane-restricted tunnels identified.

RESTRICTED TUNNELS
None identified.

NATIONAL TUNNEL RESTRICTIONS (MAJOR ROUTES)

| Tunnel | Location | Alternative |
|--------|----------|-------------|
| Holland/Lincoln Tunnels | NYC, NY | George Washington Bridge |
| Baltimore Harbor Tunnel | Baltimore, MD | I-695 bypass |
| Eisenhower Tunnel | I-70, CO | Loveland Pass (US-6) |
| PA Turnpike Tunnels | PA | I-80 or US-30 |
| East River Mountain | I-77, WV/VA | US-19/460 |

WHAT COUNTS AS "PROPANE"?
• RV propane tanks (even if turned off)
• Portable propane bottles
• Propane-powered generators
• Note: Gasoline/diesel vehicles are typically fine

TIPS
• GPS apps like RV Trip Wizard route around restrictions
• Turn off propane at tank before entering any tunnel
• Watch for "Hazmat Prohibited" or propane symbols
• Some ferries also restrict propane - call ahead

SAFETY
If you accidentally enter with propane:
• Do NOT turn around in the tunnel
• Keep windows up, don't run fans
• Proceed through at posted speed
• Report to authorities after exiting

RV Weight Ratings Guide

Understanding GVWR, GCWR, and weight limits for RVs in Montana. 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
• CAT scales at truck stops (~$15)
• Public scales at quarries, recycling centers
• RV rallies often offer free weighing
• Get segmented weights (each axle) for proper loading

WEIGH STATION REQUIREMENTS

STATE POLICY
Only business-owned RVs over 8,000 lbs must stop

WHICH RV TYPES MUST STOP?

Based on the 8,000 lb threshold:

| RV Type | Typical Weight | Must Stop? |
|---------|----------------|------------|

TIPS
• Weight on door sticker is GVWR (max), not actual weight
• Get your RV weighed at a truck stop CAT scale (~$15) to know actual weight
• When in doubt, pull in - officers are usually understanding with RVers
• 'All Vehicles' or 'Vehicles Over X lbs' signs override general exemptions
• Commercial or rental RVs may have different requirements

PENALTIES
Skipping a required weigh station stop can result in:
• Fines from $100 to $500+ depending on state
• Potential vehicle inspection
• Points on license in some states
