I hope that works for you; however, you are installing the product where the manufacturer specifically states not to. Also, the weather conditions, if you store your RV, also violate the manufacturer's recommendations.
1. "You cannot install Allure in ....camping trailers..."
2. "Our adhesive can not get down to 15F (-10C) or not higher than 95F (35C) for an extended period of time. Long term exposure to freezing cold or hot tropical temperature will damage the floor or cause the adhesive to fail."
