Let me get this right, you are going to drop a TC once a week to go to church, but be active so far away from the trailer that you can't return home to sleep. Sounds contradictory.
Yes, I personally find this somewhat strange too. But I am trying to accommodate my DW. She likes the nature environment and hiking to great sceneries. She loves campfires. She doesn't like campfires between two trailers though. I'm not as picky but I'm doing my best to satisfy her desires within means. It may not make sense to you (and to some degree me) but I have respect her - she does that for me too. If nothing works out, we will bring tents in our car and sleep in the parks when it is desired and just buy a Class A diesel as we planned originally.
