I’ve been using one for about 6 years on 2 different campers. Before that, used an EZ Lift. There’s no comparison, as the Andersen is vastly superior.
First truck was a Nissan Frontier running at its max payload. No problem returning the front end to Nissan’s specs. Towed a 4500# (loaded) camper with 550 tongue weight. Never a moment of sway.
On the Silverado, it performs perfectly. Have about 645 tongue weight now.
Pros:
Easy, fast set up out of the box.
No grease on anything.
Easy, fast, simple hookup.
Works as it should.
More quiet than bars.
Built in sway.
Great customer service.
Comparatively light weight.
Easily adjusted for changing tongue weight by tightening or loosening a nut on each side.
Cons:
Initial expense, though lower than top tier WDs.
Probably max tongue weight around 1000 pounds (never been that high, so not sure)
Had to replace cone liner after 4 years, though they sent one gratis.
I haven’t heard of anyone dissatisfied with it.
