It sounds like you have a great attitude -- there are always both advantages and disadvantages to everything. Starting a new traveling lifestyle can be really unsettling, especially after you have honed and perfected you workaday lifestyle in a stick-built home for your whole adult life.
We've been on the road for over 6 years, and there are definitely things we miss (bicycling with our friends, regular workouts at the gym, tending a garden), but we have learned and grown and seen so much that it is ultimately totally worth it.
After full-timing for 2.5 years, we got the wacky idea to buy a sailboat and give cruising a try. It was awesome but had its huge disadvantages too, and after 3.5 years of alternating between sailboat and RV, we're selling the boat and going back to full-time RVing.
What all this taught us is that it is only after you begin actually LIVING YOUR DREAM that you can find out if you dream is truly dreamy or needs to be adjusted.
You may find you need to tweak things a bit -- modifying the rig, or replacing with another, getting involved in other churches on the road somehow, or combining traveling with returning to your beloved church community.
The thing is, this is your dream, and you can put it together any way you want!!
Have fun with it!!!
