We Love our Big Country 4010RD very much, We bought it New, Picked it up 3 Weeks after it was built. We did have some Issues, about 13 factory defaults within our first year. Heartland did a great job with assisting us with all of them. Sent parts to me and also to the dealers who worked on our RV. We feel that they need to improve the fireplace, we and many other RVers we encountered went through multiple fireplaces. I also feel that they should give a 2 year warranty and not just a one year. One of my big complaints about the building of this 4010RD is that I do not agree that they put a large A/C unit on the front that makes the height 13'6" the max any RV can be. They should put a Low Profile A/C on all that would be close to 13'6".. That would give us maybe 6 inches lower clearance then we are now. I do think that the builders need to be a little more focused on paying attention to details. Another design flaw is the sewer drain, it is to low to the ground, I had to get mine lifted about 6 inches, I almost broke mine off, it was about 5 inches off the ground. Also almost 90% of the screws in our RV were not put in straight. More Quality control in the building of Heartland campers. We are on our third year and have broken in our RV, we have had very little problems now, like moldings coming loose, LED lights going out. plastic part on windows are breaking off. Need to make these part metal especially being Full time RVs. I would have made some requests if I were to buy new again, A/C would have been replaced with a low profile A/C. The Tires would be G rated tires like the ones we have, Sailun tires, they are great tires. Have had no issues with them. Make sure all lights in and out are all LED. Show less
