Hope you have good luck on finding a good cover. I just did business with National Covers and all I can say is DON'T Bother, horrible customer service from Anthony one of their reps. I ordered the Expedition (it's their second best) cover along with the gutter spout protectors, took close to 2 weeks to get to Washington State from California, however, when it arrived I noted there was no shipping invoice and the gutter spout protectors were not in the package, but I was charged for them. Before I called them I checked my emails to make sure I ordered them and they were on the order email receipt and then went to their website to see if they were possibly backordered, nope they are in stock.
The funny thing is that the price of the cover went down by $60 during the time from when I ordered till the time I received it. I called them, waited 10 min for a rep to speak to ended up speaking to Anthony. I explained that the gutter spout protectors were not in the shipment and that I was charged for them. He didn't even apologize their mistake and just said that they could ship them to me. I explained that the price went down $60 during the stated time and would they consider crediting me the difference since they messed up the order. All I got was a BIG FAT" NO" and he wouldn't budge. Well, so now I'm returning the cover at their expense because they screwed up on the order and wouldn't try to make it right in some way or another. There are better companies out there!!!! Don't believe their raving customer reviews either since there is no way to actually post a review on their website
