I have over 75k miles with my Lance 1181 on a truck. I have driven on many 4WD backroads including 2 weeks ago on a Forest Road in the Gila NF that took me 1 hour to cover 4 miles. Been to Alaska and back over all the frost heaves. My slide is behaving like new. It reliably moves in and out and, after I got the friction adjustment correct, never begins to slide out while on the road. There are no signs of stress in the supporting structures and I did replace the awning cover when the sun rotted the fabric. I don't know what brand Lance is using now, but my slide is fantastic.
