A fifth wheel connects to a hitch installed in a pickup bed. Its raised front section extends over part of the truck bed, which gives it a multi-level layout, tall ceilings and a stable towing feel when the truck and hitch are correctly matched and loaded.
A fifth wheel's truck requirement often depends more on its loaded pin weight than on its advertised towing weight.
Quick facts
| Typical length | 25–45 ft (7.6–13.7 m) |
|---|---|
| Typical weight (GVWR) | 8,000–20,000 lb (3,600–9,100 kg)+ |
| Fuel | Uses your truck's fuel; towing raises consumption |
| Sleeps | Usually 4 to 8+ |
| Typical new price (CAD) | $40,000–$200,000+ |
| Typical used price (CAD) | $25,000–$120,000+ |
| Towing or vehicle needs | Three-quarter-ton or one-ton pickup; heavy luxury models often need a one-ton diesel |

Benefits and trade-offs
Benefits
- Spacious floorplans and high ceilings
- Large storage areas on many models
- Well suited to extended stays and full-time living
- Stable towing behaviour when correctly matched
- Some offer separate offices, bunkrooms and residential appliances
Trade-offs
- A lot of weight is carried by the truck
- Larger models may require a one-ton or dual-rear-wheel truck
- The hitch occupies truck-bed space
- Interior stairs can be a mobility concern
- Height and roof clearance need close attention
- More expensive than a comparable travel trailer
Who it suits
Best fit: Longer stays, full-timers and anyone who wants maximum living space in a towable and already owns, or will buy, a heavy-duty pickup.
Look elsewhere if: Buyers with a half-ton truck that cannot carry the pin weight, or who move camp often and want a shorter combination.
What to check before you buy
- Pin weight, about 15 to 25 per cent of loaded trailer weight, against the truck's payload.
- A 14,000 lb fifth wheel at 20 per cent puts about 2,800 lb on the truck, before passengers, hitch and gear.
- Truck axle ratings, tire capacity, and whether a dual-rear-wheel truck is needed.
- Overall travel height, written down in feet and metres, for bridges, ferries and storage.
- Stairs and bedroom access for everyone who will use it.
Canadian considerations
- Pin weight is the number that decides your truck. Use the towing and payload calculator with your own ratings, and read RV weight limits explained.
- Long, tall combinations pay more on ferries and may not fit older campgrounds or storage buildings. Check the ferry rules.
- Heavier combinations can change licence and brake requirements. See licence requirements and towing laws by province.
- Large fifth wheels need winter storage with enough height and gate width, so plan that before you buy.

Common questions
Do I need a one-ton truck for a fifth wheel?
Not always, but large fifth wheels often need a three-quarter-ton or one-ton truck, sometimes with dual rear wheels. The decision depends on pin weight, axle loads and tire capacity, not the advertised tow rating alone.
What is pin weight?
It is the downward load a fifth wheel places on the truck through its hitch, usually about 15 to 25 per cent of loaded trailer weight. It counts against the truck's payload.
Are fifth wheels more stable than travel trailers?
They can be, because the hitch sits over the truck axle. That only holds when the truck, hitch and loading are correctly matched.
