We're currently in San Antonio and were delighted to see a 3850rl at our campground. Owner is from Canada and speaks very little English but it was nice to meet him anyway.
In Deming, NM we met Jimmy (2012 Trilogy don't remember the floor plan). He knocked on our door to ask if the (this is where I DONT have the ability to use technical terms) outside floor of the slides were separating near the edges? Ours wasn't/his was but he pointed out the 'angle irons' holding the bottom attached to sides was wider on ours.
Please post your sightings on here.
