I agree with most of if not all of the above. I found out too late that the 2000 Hundy's had "hand grenade" tranny's - a $4K pill to swallow. The pin got pulled on a hunting trip 200 mi from home. Replaced trans at ~ 122K mi with stronger factory rebuilt unit. The factory rebuilds are alleged to have fixed the the original OEM problems. So far, at 154k mi mine is running fine and strong.
The ABS system can be a problem, too. If left to sit too long or if not properly maintained it can be a... $3.4k problem. Mine went out at 143K. Another of those jagged little pills. Flush and replace brake fluid regularly as per FSM and you'll probably avoid it. If and when it goes you'll know. The dash will light up like freebie night in a brothel and it will sound like someone is strangling a cable newscaster under the dash.
Apart from that...I have come to really love this truck.
It has taken me places I wouldn't walk and gotten me there in comfort and otherwise has been highly reliable. So far, it hasn't failed to take me any place my buddy's 80 could go (but our rag-tag group may not be as hardcore as some others on MUD). It is an excellent blend of highway comfort and rough road/almost no road, go anywhere wheeling awesomeness.
It also has substantially more power and better fuel economy than the 80 series though it does lack a solid axel front end. IFS can be a bit of adjustment and with an AutoHome RTT on it can feel a bit wonky. But who hasn't spent a dozen or so hours on the road getting to where the real wheeling starts in their 80 and felt like wet dog wobbles on arrival, only to face erecting a tent in howling wind in the dark? Not me. I arrive in comfort and in less than twenty seconds am upstairs in bed looking forward to unknown roads and wild views the next day.
Despite its congenital problems (now fully corrected and functioning better than ever), with some help from the folks at Slee and a lot of help from the kind folks and forums in the MUD community, my rig has evolved into one heck of an expedition vehicle. Don't hesitate to consider one.
