Welcome FarmerBill and wife ! You will find this form a GOLD mine of information. You will want to spend the $12 and become a sponsor. This will let you go to more detailed information than a "trial member". I studied the information for five months before we got our 2006-2720. I am still learning from the other members on the form. Yes, there is a bunch of mechanical things to learn, but you will be in good hands on this form. Good Luck!
