Hi! I'm also in Colorado and used our brand new X17A for the first time last weekend. Talk about newbie - I never even had a hitch before, nevermind towed anything. There are some great YouTube videos about lighting the water heater, the oven, hooking up the hose, and dumping the tanks. I watched several of them over and over again. I also posted specific questions on this forum, and the people here are wonderful. I also video' our delivery, which wasn't great. Let me know if you want me to send them to you.
I found this video helpful. It's an older year and some things are different, but it was helpful
This video was helpful for the tanks. The set up is basically the same even though it isn't your model.
Search by subject on YouTube. I found a great one last night about how to use my electronic break control.
Let me know if you need anything!
