Glad you decided to join in like2. I agree there is a lot of great information on this forum that helped give us the confidence to ER last year. Do you plan to be a full time RVer when you retire? I have read quite a bit about workamping and it sounds like some of the gigs are pretty nice while others maybe not so nice.
Good luck with your four year plan. We had a five year plan but it actually ended up taking us eight years to cross the finish line thanks to the Great Recession a few years back. Regardless, you have to have a plan.
