Thank you John!
Now I can stop posting purchase questions and start posting "how does this work?" questions. There is so much stuff to learn, but it's a good problem to have!
This is step 1 in our pre-retirement check list, to be followed by a newer toy hauler - the current one is going in Monday for a new roof under warranty, but we won't keep it long. Bigger and better, and everything paid for before retirement.
Read your blog BTW, very nice!
Regards!
