I don't see isolator?.....when they go into big rigs, they don;t get an isolator....because there battery bank is so huge...
so your 850 PLUS the cost of battery...still way cheaper then Michigan
$865 is Espar only...Isolator , battery and other wiring extra....IE: fusable link.
the beauty of the TK house brand battery is its 3 year FULL warranty....none of that prorated crap...
I understand what you are saying completely.....and I agree...but that is not how these guys work...Its like them big ads for the 5,000$ sign on bonus in big flashing letters....BUT there is the SMALL print to bite you in the butt....
the ad doesnt say battery and isolater stuff included ....the big rigs run it off their huge house batteries...so that is not included...one would have to call them to get the low down...
that would mean communication between OnTime Media and the carrier....they ain't going to change it every week or so...carriers needs change almost daily....
