Tow Vehicle Recommendations?

["Scott Janzen" <s.janzen@comcast.net>]

I'm towing a  22 box trailer (Haulmark) with a GT6 inside.  Current
"tractor" is a 1990 Suburban, which is getting old and crusty.  I'm looking
to spend not more than $14,000, have so far focused on '98-99 Suburbans,
which can be had for that number or less with under 60K miles.
Anything else I should look at - relatively inexpensive and reliable?  I
want to stay in the SUV family to use it as a people hauler too.
