Tahoe has the most bulletproof drive train out of the 3, although the Toyota is awful close, if not right up there besides it. The new 4Runner is awful looking (this is just a personal opinion, lol)
definitely happens, but like Craig mentioned the guys that got stuck twice should be paying heft hefty fines, that's just Darwinism at work if you ask me.
Also, why are you fishing rivers when they are blown out and chocolate milk in the spring? LOL
You probably don't have your Garmin setup properly if you're not getting ft by ft contours on it. I've got Bluecharts on my Garmin 62S and have no issues getting great detail with it.
Happens to a lot of cars.. My gf's Murano is suffering from the exact same thing. I need to pull the rear wiper and 'un-seize' it for a lack of a better word.
I doubt it, just bunged up with a lot of salt. Have had it happen to a few of the Saharas I've fished in saltwater. Nothing a once over with a toothbrush, some fresh water and a light oiling won't fix.
