First of all wanted to thank everyone. I purchased a Screw 2 weeks ago and notified
the Dealer I had the wrong radiator (1.02 vs 1.42")...after 3 phone calls they ordered me
the 1.42" and it should be in soon.
On the topic of tow package upgrades...How
can I check to see if I have the upgraded
battery and alternator (HD Electrical 72 amp
hour battery and upgrades Alternator)

Are there part numbers I can see and compare against or use a volt/amp meter to measure
output of the alternator/battery ?

Thanks in advance, Tmeyers-Colorado
