thinking either 02+ or 05+ grand Cherokee.

my pilot is still running strong. only has 112k miles. its great. I tow my 14ft flatbed back and forth from vegas all the time.

problem is its seats suck bad. very uncomfortable.

looking at maybe a grand Cherokee to replace it.
any tips from other gc owners?
which is more reliable?
should I get 6cyl or v8?
real world milage you guys are getting?

need atleast 4k towing
must have 4x4 or awd
