Welcome to our forum.
Something for potential new tub owners to try. Yes, your dealer is the front-line person for customer service, but take some time and email/call the manufacturer and ask questions BEFORE you buy. See how long it takes them to respond via email. How long were you on hold on the phone? Try different times of the day, and see if you get different response times, answers. Its not everyday you have 5-10k to drop on a purchase, make sure its the best one for your money.
PS Do people spend this much time and energy deliberating over purchasing things like four-wheelers seadoos or snowmobiles?
