1.0 out of 5 stars ABSOLUTELY A WASTE OF $450
By chuck on August 23, 2019
"Tyveck plus wind" . I put it on April 1st by June it had 8 holes in it. There is a 8' tear in the front. (see pictures) the warranty is a joke. They'll send you patches or replace it 1 time for life. What a misleading bunch of BS. As you can see theTyveck is tore in the middle. I doubt it is Tyvek. Have you ever tried to rip Tyvek? If you are looking for a $450 dust cover because you park your rig inside, well this would work probably. That is if no one sneezed near it, then maybe not.

1.0 out of 5 stars Save your $$$ - DO NOT BUY!
By Brian Doersom on July 11, 2019
I have a 2017 Palomino Puma. I am the original owner. I purchased this cover on April 17, 2019 for storage outdoors and "reassurance" that my investment would be covered from water, UV, etc.

When going to do my monthly inspect of the cover, I found it in the state you see in the photos attached. Rips everywhere, completely unacceptable for something I dropped over $400 to purchase.

This cover is inferior, product quality is horrible, difficult to install... Would not recommend to anyone to use.

The product actually ripped in several places on my camper. It was not over sharp objects but things with rounded edges and made of plastic. You can see these tears in the images attached. I have since decided to just store my camper indoors.

Called ADCO. Their Warranty states 3 years and ONE replacement. So, if this thing rips in 90 days of use like it did with the first product I'm just out $400+ dollars. Unacceptable. Figure out a better option for your toy, this is not it!

1.0 out of 5 stars Not worth the money
By Joshua R Jones on January 15, 2019
Purchased this to protect our camper and liked that it had a three year warranty. After being installed for a month cover ripped. Contacted company for warranty and they was willing to replace it but that would be my one replacement and I would no longer have a warranty. Don’t by name brand and just buy a cheaper one. Will last just as long and the warranty doesn’t really mean anything. Said they would send me patches for free but that doesn’t fix something that broke after only a month!
