Can a 1997 Jeep Grand Cherokee Laredo be towed behind a camper?
If it has a manual trans... easily yes. If it has an automatic transmission, you will need to isolate the drivetrain from the transmission, or else you will burn out the seals & bushings. For 2 wheel drive vehicles, this means removing the driveshaft & installing a shipping plug in the rear of the tranny. For 4x4 trucks, you can usually accomplish this by placing the transfer case in neutral.
There is no such thing as a 2002 Cherokee Laredo. The last year for the Cherokee was 2001, and the last year it came with the Laredo trim was 1992. I have a 2003 Cherokee Laredo so this awnser makes no sense at all. Do you have a GRAND Cherokee Laredo? Those are still being made. They are not the same as the Cherokee.
