We have a 2013 Heartland Landmark San Antonio model. We left Colorado Springs May 1 and went to Soldotna, AK for the summer. Long trip and took our time. We took our time on the return and now we are in Santa Maria California for the winter. We put a freezer where the washer and dryer goes, and still have over a hundred pounds of salmon left.
My unit has had it problems, nothing major, just like anybody's else new rig. I have had good service from the factory customer service. Each dealer repair shop has had its issues. Some good, some bad. I deal first with the factory and follow through with the dealer shop.
My neighbor has a 2013 Big Country and has had no problems, but he only has a 500 miles on his rig. I love his floor plan, but not his level of conponents and finish. I would have jumped up to a Bighorn or Landmark, but its not my business to know his financials, or his taste. He likes his rig and I like mine. I just like a few more bells and whistles. We are both fulltiming, and the 2+5 warranty did play a factor in the decision.
Don't think you won't do a few mods to make it more like home. Look at the mods on this forum.
You are going to spend 10's of thousands of dollars of your hard earned money, so get what you can afford and enjoy. Good luck.
