Thor Four Winds 30W vs Jayco Greyhawk 29MV

Thor · Class C

The difference that matters

Close on almost every number: both are about 32 ft on Ford's 7.3 L V8 with a 14,500 lb GVWR, both sleep five and both have a rear queen with theater seating. Price is near too, around $164,000 for the Four Winds and $174,668 for the Greyhawk.

For the extra money, the Greyhawk 29MV adds heated holding tanks, automatic hydraulic leveling jacks, heated remote mirrors, 200 W of solar against 100 W with a second house battery, and bigger tanks at 47/41/32 gal against 40/30/25. Its walk-around queen comes with nightstands, and it has a 4,000 W generator with auto start and a tankless water heater.

The Four Winds 30W counters with a sofa and dinette slide, a mid split bath, a 4.0 kW dual gas and LP generator, ducted A/C, washer and dryer prep and an 8,000 lb hitch. It is also lower, 11.2 ft against 11.7.

Thor Four Winds 30W: Heavier-trailer towers, as a couple or small family, who want washer and dryer prep at a lower price.
Jayco Greyhawk 29MV: Travelers who camp in cooler months and want heated tanks, auto leveling and more water.
