Used my Lance 981 in weather from 7f to 115f. On extremely hot days the A/C would not provide much relief unless it had been running before the hottest part of the day. Our use of that camper frequently landed us in Mesquite NV at about 4 in the afternoon. The digital thermometer would be pegged at 100+. No way the A/C was going to bring it down quickly. The solution was to go to the pool and leave the A/C running. Return after dusk.
On the other hand, during the winter camping in New Mexico and Colorado it would get darned cold. We never drained tanks or added RV anti-freeze. The 4 season features worked as advertised.
Of course we are home based in So Cal so we never need to winterize because of the local conditions.
