I'm currently in the market for a new 5th wheel, and as a 10+ year travel trailer owner, I agree with the comment about brand loyalty and cult followings.
Right now, I'm looking at small 5th wheels in the 32-36' range for our family of 4 and our dog. No luxury brands for us. The usual suspects are being considered. Jayco, Rockwood, Grand Design, Keystone. While there are certain makes that I like a little better than others, I can't for the life of me imagine getting so burdened with brand loyalty that I lose sight of what I consider to be other significant purchasing data points. Dealership, COST, location of the dealership, etc. For example, I really like the Grand Design, but the nearest dealer is located 200+ miles away in another state. The Rockwood, which I also like, is located 8 miles away. The Jayco, is located 25 miles away. Even if the Rockwood has 4-5 service issues, I'll be able to zip it over to the dealer in 20 minutes. That's pretty important to me.
I guess for me, having climbed in and out of so many campers, I don't see *that* big of a difference in build quality and fit and finish between the different makes within the class that I'm looking at.
