First, I believe you will find that the location you are referring to is no longer the Lazy Days resort, but is now owned and operated by KOA.
As for a mobile service, I would check with the resort office. They may have a list of names. Many times, they will not allow mobile services providers that have not registered with them to work on their property. They likely require an insurance certificate from the repair service to cover the resort from potential liability. It would not at all be unusual for the resort to require a minimum of a million dollar liability policy naming the resort as an insured to allow them to enter the resort and provide service.
Also, I am with Executive, why not visit the Lazy Days service facility?
