Jeep XJ Forum

JMHO
All at one time = bad idea!!!!
I hauled a pallet of landscaping bricks in my 82 Wag and it was squatting very low in the rear and made it a little hairy stopping and turning corners.  It seemed a little squirrely too but it managed to survive.
I would NOT subject an XJ to that and would use a rental trailer instead balancing the load so there it not too much weight on the tongue while putting some weight in the cargo area of the XJ!  That is how I hauled concrete with my XJ to make my concrete parking pads.  ;-)
