RV'ing , almost by definition, involves lots of DIY or "honey-do's" to
keep the rig in tip-top shape, especially since it travels over bumps in the road at 60 mph ! Having said that, the Heartland products are just wonderful - well designed and well constructed. This is a company that stands behind its products, too, and really looks out for the customers. So if you do have problems, you won't be left "hangin' in the wind".
We've had ours since last Nov and haven't had anything wrong, other than REALLY minor stuff - all major systems and appliances are terrific, as is the fit and finish.
Remember that forums are also a place to get advice from other owners when there are issues, so you're going to read more bad than good, in many cases just because that's how the forum is being used.
I strongly recommend Heartland products - I say GO FOR IT AND ENJOY THE PROCESS !
