Keystone Hideout "quality" ?

I would try keystoneforums.com as you are more likely to find actual owners. I own a Cougar and can't speak to that model. You do know that is a bunk house model and that means you could have small people stowing away while you try and relax and get away to camp. Hmmmm KIDS! That's what they call them... almost forgot. Seriously, looks like a nice family trailer. The F350 should be plenty of truck for that trailer as noted. Just one more note, if the trailer is somewhere being sold in a galaxy far far away, keep in mind most dealers don't much care to honor warranties or work on trailers they didn't sell but you probably already knew that. Lots of folks on the Keystone forum go traipsing off to discount sellers thousands of miles away and then find that the local Keystone dealer doesn't know them... good luck!
