Thanks, PH. We probably won't do a lot of boondocking but I'll never say "Never" to it. We will be towing a dinghy so it's likely we'll park the RV in a campground and drive the dinghy to go exploring. It'll be a 4x4 so we can hit a lot of the back roads and trails.
BTW, at the highest, my PSA was about 585. It's now 12.2. Not where it needs to be but it's a lot better than that 585 number.
I meet with my oncologist on August 10 so we will discuss the progress made and where we go from here.
