I go shopping the 1st of October for Christmas gifts because stores are starting to have Christmas sales. I give someone a present on Christmas and the following week they try it out and it is defective. Gee, sorry, can't return it, it's past 90 days.
Same issue here, the camper was closed up, and not ready to use until last week. You might think 90 days is 90 days, but to me it's poor customer service if you can't make exceptions like this. Clearly the item is brand new. If I had been using it over some time, I would never expect them to take it back, that is what warranties are for. However, if an item is new, different story. It could have been sitting on their shelf all this time. I guess you do all your Christmas shopping les than 30 days before the holidays in case the stores only have a 30 return policy?
