We are thinking the same thing the steps in and out are getting harder to do. Climbing up and down the bed to get that shirt you forgot to take out before you got out of bed.It's starting to take a toll on us. We have been looking for a used Chinook pricey when new but molded fiberglass construction means no climbing on the roof to check seams. There are other brands out there but I've seen a few Chinooks and I like the looks of them.
