Hey Rooskie, welcome aboard. We bought the same rig last year (our 1st RV) and LOVE it. No problems in the first 4500 miles of traveling. One thing I did was to give it a good wash and coat the roof and all sides with 303 protectant. It is an "SPF" for your rig. Protects from the sun & minimizes fading. You may want to put some Rejex on the front-end cap is help ease the bug removal, but the 303 is also very good for that.
The only other thing I might suggest is to get in it and enjoy it! Smart move to get into Heartland and to log into this forum. You will find a wealth of info, great advice and super people.
We are getting more involved with Heartland rallys this summer. I suggest you do the same. These Heartlanders are always willing to help you out.
Hope to see you at one of the rallys and meet you in person. Until then, Happy trails to you. ENJOY ! !
