Hi Lefty and welcome to the Shack!
The 810 may work for you... it is hard for me to say for sure though. If there is a Universal dealer in your area, you might prefer to purchase from that dealer and let them do the install.
We have a
Houston group that gets together all along that may know someone in your area who can help you set it up. You might try posting in that thread. Also, one of our administrators, Wayne Pflughaupt, is from Houston... he may also be able to help.
