You can sing, girl...I just checked your Facebook page. I hope you have room in your rig for your keyboard.
Don't be afraid to take off on your new adventure by yourself. I took my first big trip this past July ...drove from TX to OR alone and it really was much easier than I had anticipated. Regarding the lack of heat I would take BirdbyBird's suggestion and get a small electric unit. I have one and it works great. I use it more than I use my propane heater. I got mine at Walmart...very inexpensive.
I am in Wilsonville, outside of Portland, and there is a Camping World across the highway from me (I-5). You could stop by there and let them look at your unit. I am taking my rig in tomorrow as I had smoke coming out of my water heater. Tried cleaning it but it still smokes so I am without hot water.
Hope we see you at one of the "get togethers." You could be our entertainment or maybe get us all to sing around the campfire. Fun!!
