Our experience has actually been great! Our home church, a Foursquare church in Oxnard, Ca has grown to over 2000 every Sunday. We we're very involved and our son still is on the worship team and works at the church.
We have been fulltiming for over 1 1/2 years and realized early on we couldn't just find our denomination. Every week we trust in the lord to place us where we belong. Obviously I am diligent to check out as best I can, but as a good brother told me if the spirit of God is not there before you arrive, God will be there when you get there. :)
We have been to Baptist, Methodist, EV Free, Calvary's, Foursquares to name a few and the power of God has been in all of them. The smallest had 26 including us and the pastor (I know because the pastor commented about it during service), up to about 7000 in a megachurch we went to. We have been warmly welcomed in all by the pastor in the small/medium churches or by hospitality teams in the larger churches. All seamed really interested once we revealed we were full timing rv'ers.
We LOVE our home church and enjoy when we are visiting family at home as we are now, but it has been fun and exciting to see what God has in store for us each week.
God bless,
Brian
