If change is my friend, why do I feel so anxious?

My husband and I took the next obvious step in our RV adventure and bought a fifth wheel today.  It is exactly what I think we want. We spent a couple of months seriously looking at fifth wheels and picked out this make and model as our first choice. I wanted something used, preferably about 5 years old. This 2014 Arctic Fox 27-5L fits the bill perfectly. The price was a little more than I hoped to pay, but we went through a local dealer in California and all of the internet reading I did indicated that we would pay a higher price in these conditions.

So why I am awake in the middle of the night feeling anxious about this purchase? I am not having worrying thoughts. I just have an anxious feeling in my gut. My only explanation is simply that I am nervous about the change we are bringing upon ourselves. We have to learn how to drive this thing, back it into campsites, and take care of all the maintenance items that I'm totally unfamiliar with. This is the first time in my life where a big change that I chose myself is making me anxious. 

My parents bought a ski boat and a travel trailer in their mid-40's for our family, but my mother usually took us camping on her own. My dad loved those weeks at home by himself when he could take care of projects around the house, like re-tiling the shower. Mon was passionate about being outdoors, and since she had nine children to take care of, she had to bring us along. She jumped in head first and learned how to drive the boat safely, pull the trailer, and deal will all the unfamiliar systems in the trailer. I am now gaining some appreciation for how impressive she was, acting with confidence in the face of change.

Our vacations with the travel trailer were all excellent. We visited most of the National Parks in the Western United States with that trailer. I never experienced tent camping as a child, but I certainly appreciated a solid roof over our heads when it rained across most of Oregon and Washington. Those childhood memories is what set me on the path to buying my own rig now. I want the experience of being in wonderful places, but still have the comfort of the trailer to protect us from rain, snow, wind, and mosquitoes.

I will use my mother as my role model now. I may have to fake it at first, but I am determined to act with confidence in the face of this change.
