I feel for you. My dw's parents also require a lot of our attention. We can only leave on extended trip when another family member will step in to help. That said, I waxed,winterized and put the tt to bed for the year three weekends ago. I have two grandkids in texas and when they called and said they wanted to go camping, well I said I'll see you for a week the last of October. My arm still hurts they had to twist it so hard.
My carlisles have about 5-6000 miles on them I hope they will last another 2.
