Hmm, so $18K is a Quigley 4x4 ($12.5K?) and PH Top (5.5K)... put into a 2000 van with 177K only months ago? While the Diesel should have a lot more life, that's not exactly worry free mileage.
I honestly can't tell if this is the starting-point of the century or fishy. Getting next to new PH and 4x4 system... but no interior trim, it's just really hard to say.
(*Hmm, I read 4K miles ago as "months ago" for some reason... that doesn't help any
I'll be curious who is into this and what other people think)
