Hi PainWhisperer,
Welcome to the Heartland Owners Forum and Family. We have a great bunch of people here with lots of information and all willing to share their knowledge when needed.
When you go to pick up you new Big Horn,,, do a very slow PDI... have your dealer have everything hooked up,, water, sewer drain, tv..electric...... make sure you can operate everything and everything operates... even to heating water in the microwave,, flushing the toilet,,,draining the tanks and all. From hookup to unhook.... Even take a video camera and record as necessary. Then camp, if possible, on the dealers lot where anything you find can be adjusted or fixed before you take final delivery.
Let us know how it goes and if the Heartland Family can help,,, we are here for you.
Again ,,, Welcome to the Heartland Family.
