THANK YOU everyone for all of your input. Always can count on multiple ways to look at things on this forum and I LOVE it.
My actual plan is every month on the 1st, 2nd & 4th Saturday there is a CnC I plan to attend...unless it rains (

Rain???...I live in Arizona...actually supposed to rain this whole week

).
However. here the summers can be brutal...last summer broke the record for number of days 110 or more. Also the car scene slows WAY down...due to the heat.
So usually from May - Sept will only take it out every other week (CnC 2nd & 4th Saturday) to keep things moving. Along with a few trips up north Arizona to escape the heat!
So all in all I think I will be good not needing a trickle charger but based on all the responses I will hook one up if I think the car will sit longer than 2 weeks. Now I need to search on the best way to hook on up on our cars in case I need to use mine.
Thanks again everyone and be SAFE!!!
