What to know before buying

Listing details to confirm

Capacity figures are not fully consistent: the listing gives 550 pounds maximum and 330 LBs dynamic capacity. It also advertises 300L storage, while its structured dimensions are 39.5"D x 21"W x 25"H. The title and feature text describe all-terrain wheels, but wheel performance is not established by those claims. Customer feedback differs on steering and reports mixed wheel durability, including reports of wheels coming off after one use. Confirm the load rating and fit for your intended cargo before buying.

Who is it for?

A good fit for

People hauling beach, camping, garden or sports supplies who want a folding cart with a tailgate.
Buyers who value pockets, cup holders and an adjustable handle for organizing and moving outdoor gear.

Less suited to

Anyone needing a verified single load rating or proven wheel durability for frequent heavy-duty use.
Shoppers who need a lightweight wagon for frequent lifting, given the listed 31-pound weight.
