Bought the 2024 Thor LEMON (Thor Aria 4000 - Class A diesel pusher) new off the lot. AquaHot system sporadically made hot water at first and then none at all since - nearly 1 year later. After spending months (literally) in the shop at Lazy Days of Wilmington, Ohio, hours on end with tech support, 2 days with an AquaHot-licensed professional at my house working on the unit in my driveway, and 2 weeks at the Thor factory repair in Wakarusa, Indiana (the factory where the Thor 2024 Thor LEMON was made, I still don't have hot water. This makes it a LEMON in the State of Ohio, which is so regretfully my last and only resort; after taking cold showers for a year... the level of incompetence is simply baffling.
Recommendation: DON'T DO IT. BUT SOMETHING ELSE. YOU'LL BE COMPLETELY ALONE WITH YOUR ISSUES
