You might explore why your remotes are dying. I probably operate my
door at least two or three times a day most days, and my three
Chamberlain remotes have been working for at least 15 years. Maybe
they need to be ruggedized somehow for the service they see on
tractors, or something. The weakest part of the remotes is the
plastic-flap-actuated circuit-board contacts. Bypassing those with
weatherproof and gorilla-proof pushbutton switches might enhance
remote lifetime considerably. Renewing batteries once a year wouldn't
hurt either, though I don't recall when I last renewed the battery in
any of my remotes.

Thanks for the advice. I'm sure the biggest problem is tossing the units in
the tool box (dirty). I'd tried taping to the steering wheel but range
became terrible and then they get rained on. I've already installed an
outside antennae for the opener - very little help.

Another possibility is that you have a noise source that is
desensitizing the receiver. If possible, it might help to relocate
the receiver and run relay wires from it to the opener mechanism --
rather than have the receiver co-located with the mechanism and run
antenna wire.
