It’s not though, I deal with galvanic corrosion all of the time, same, deal with it daily, it’s not “rust” but the paint will fail as you know....that is 100% the onset of galvanic corrosion. JMHO, I’m not getting in a pissing contest with you, but I’ve seen this in this exact application...
I’ve purchased hotheads in the past and loved them, this round I ordered the mopar ones because it was easy...you probably can’t go wrong either way, but if you don’t order it with them I’d probably opt for the hot heads again to support the smaller business
I ordered a 2021, I’m between 6-8% off invoice...OP just put the whole package together then barter price....if it’s a lot vehicle barter price and then you may be able to get bed liner, side steps, or slush mats thrown in if they aren’t in the vehicle already.
I’m a jeep guy, I’ve owned a ton of them...The Grand Cherokee is a very nice long distance cruiser, the wrangler/JT is a fun cruiser but if I was constantly covering long distances as you’ve described I’d look for something more suited imho.
