Real cost of full timing

Your plan sounds good, except you will not be eligible for Medicare till 65. But if you manage your income properly you will be able to get an ACA plan for something reasonable till you get there. SS income is only partially taxable and Roth IRA's are non taxable. We have been able to convert most of our regular IRA's to Roth's over the years so, for us, it's a matter of withdrawing the right mix of Roth, IRA, SS and capital gains to avoid taxes all together. Our budget is about 72K per year. You can save a tremendous amount of money by utilizing NF campgrounds when you can. We spend about 3 months each year in BC and the Rec. sites there are free...no electric or water, just pit toilets, tables and a fire pit, but they are mostly on lakes I want to fish and camp at anyway. Realize though, going in, that you won't likely be able to camp till you die, so plan for your last few years.
