We also have the same unit (27RLSS). During our first year it seemed like it was at the dealer more than in our driveway, or out camping. Nothing really major, but my theroy was it's under warranty, why should I fix it? Warranty expired in April, in June we went to the rally in Goshen, left there, spent 1 day at home (KC,MO), then left to go workcamping on the Front Range in CO. We lived in it 24/7, and really didn't have any problems. It's amazing that we lived in 275 sq. ft. for about 4 months, and BOTH of us survived!!! Don't be shy about the warranty, use it!!! Also, like has already been stated, if you have any questions & can't get an answer ask the forum, you'll get answers here! Also, go to a rally, we went to our first ever in Goshen, and are hooked! We are going to try to be the first ones to sign up for the rally in Gillette! From what I've expirenced, Heartland is a great company, excellent customer service, and quality leaders heading the company.
