I've owned 2 of the ADDCO covers and have a love/hate relationship with them. I love the way they keep the rig clean, but hate putting them on and taking them off. I also hate the cost, over $300 for the cheap Tyvek cover with the white top, plus the fact they only last 2-3 years in the hot Southern California sun. BTW, the ADDCO "warranty" will get you 1 free replacement when the original does not make it to the end of the warranty. Like posted above, there are covers and there are "covers", like the ones made from Sunbrella material which cost $900 and up depending on length. Another good brand I might look at down the road is Goldline as they get pretty good reviews but cost more than the ADDCO Tyvek.
