When we bought our Bighorn, it was all about the rear kitchen floor plan. We knew little about Heartland and whether their products were superior to others. We had owned a 24' TT for 7 years and wanted something bigger as we were planning to spend a lot more time in it. We took delivery last May and in a 5 hour pre-delivery inspection only found one wiring issue and a couple of drawers mis-aligned. We have used it about 120 days and travelled close to 10,000 miles so far in the first year. I had to re-glue the pipe and fittings for the toilet, had one failed tire, had an awning recall (Dometic product) and the hydraulic system had a bad motor which was replaced under warranty. We took it out after 4 months of storage last week-end and, as expected, we had no problems during or our four day trip.
We expect to spend more than 100 days in her again this year. We feel that this model would work for us for full-timing although we have no immediate plans to abandon our immovable house. The Bighorn and Landmark models both have warranties that cover full-timing. Most brands and other Heartland models exclude full-time use from their warranties.
We didn't learn about this forum until after we had ordered our rig. It's a great resource for research prior to buying! I do note that other brands also have owner forums but this may be the only one that was set up by the manufacturer for their owners with employees who check it for new ideas and to identify potential quality improvements.
