I have to start my toad around every 250 mile per owners manual.
Haven't had a dead battery in 6 years of traveling. Never could understand all the posts about dead batteries, running charger wires etc etc.
That is until the one time when I was I was close to my destination and blew off the 250 mile start. Arrived......with a dead toad battery. Didn't realize that my starts for the trans also charged the battery. :S
Sooo "I" know for a fact that if you start it for 5-10 minutes every 250 miles, when you stop to rest or fuel up, it keeps the battery charged! :B
I'm surprised at how many of you have toads that you do not have to start them to keep the trans oil cool. Baring the ones that have installed disconnects.
