i bought this rear cargo/seat so that i could ride my daughter or wife 2-up. it's sturdy, virtually waterproof, and accommodates a passenger perfectly. Installation can be a little frustrating when trying to place the u-bolts through the rear rack, but once installed it's not going anywhere. Provides tons of storage space and it's designed to carry small gas tank for reserve fuel. At the price, you can't beat it.
My grandson has had one of these ATV boxes for 7 or 8 years
I ordered this particular box because my grandson has had one for 7 or 8 years. I always liked it. His dad ordered one last summer just like it. Now I was the odd man out, so I ordered one this year for myself and one for my brother. All four of us now have one of these boxes. They are extremely durable and strong, and very comfortable to rest against. The pictures I posted show how it looks and functions.
