I do not have the 3610, but I do have the 3600 re so, I can tell you from personal experience about your upcoming purchase. I picked up my new ,order specific,2010 in Elkhart IN April of 2009. I STRONGLY reccomend that you re-think purchasing a Heartland product. I love the lay-out of mine but the quality is just not there. Structurally I suppose it is sound and it tracks/tows well but I personally have had entirely too many issues with the plumbing, electrical etc. for a coach at that particular price point. My ac/dc converter was mounted directly benieth the toilet with absolutely no access panel, guess what happens when a pex pipe fitting fails on a summer afternoon ??? The leak will fry the poorly placed converter. I have honestly learned to laugh at the new and ingenious ways my water supply system finds ways to fail on me at the most inconvenient times. I have literally had to fix hundreds of leaks, fixtures, etc. Good luck
