Hi Chris,
I haven't been on this forum in a long time so I missed your question. Sorry about that!
Yes, I'm still pleased with my Samson tires. We're over 20,000 miles with no issues at all. I park indoors most of the time while we're home, but I don't bother with covers or anything while we're camped for a week or 2 at a time. I've not seen any sidewall cracking or anything else to cause concern.
My tire dealer tells me that I can run these tires for 7 years, then sell them for half of what I paid for them to the local ranchers for their stock trailers. We'll see how that works, but even without that "bonus", I'm happy with them.
