Rv water leak. No water for 4 days Awning broken from storm
Finding Geoffrey was a godsend!! As three older women in a new RV, we found ourselves in a bind. Unable to find anyone to help. We found Geoffrey and he was at our campsite within the hour. I cannot thank him enough. Not only did he do an amazing job, he was very kind and polite. He was more than reasonably priced and would refer him to anyone that needs an honest, nice, and knowledgeable technician. We will always use Cornerstone for all our future needs. (Which are plenty and he will be back next week to continue helping us ). His customer support was superb. His kindness not forgotten.

Schwintek slide repair
Had problem with a Schwintek slide on my trailer bedroom. Greoff came to my campground on time and assessed the need to replace one side due to slipping and track damage. Apparently the version of my slide is discontinued. Geoff called around and found a repair kit for my version. Saved me from having to replace both sides of the slide. He replaced the one side and it works great.
