I'm still curious as to whose insurance covered this, did I miss the post? Was it yours or the brokers? My fam sold their insurance biz, but I've seen 1st hand cases like this where coverage was denied b/c the vehicle in question was being used well beyond it's limits, no different then getting into an accident with say a 1/2 ton truck towing a 38ft Cigarette... bye bye insurance along with other fines (happens a lot down here in FL lol).
That Tahoe was def not up to the job, they also have very soft suspensions so even if your within it's "limits" any sway or cross wind can still get the T's bucking b/c of how soft they are. What year was the Tahoe anyway?
Either way, congrats on getting your money!
