Bought 2014 **** used and have used 8 times in 2.5 yrs. Last trip noticed slide was not sealing evenly. Top sealed but bottom was 1 inch from being sealed. Took to repair shop and they said slide was probably installed improperly at factory and became worse with use. Contacted Lance, and of course no coverage. $1600 estimate for shop to remove slide, replace rails and possibly gears. There is an adjustment for right to left located in left front left storage but there is no adjustment for top to bottom. Have also had front window leak issue but remedied with sealant. Had leak under sink and found cracked drain trap.
