Nissan Pathfinder, Pathetic suspension shown again

My Toyota 4Runner is no better with a 7,000 pound tow capacity. Even loading up presents and luggage for Christmas this year makes it sag, much less actually towing anything. I definitely think of it as the Sag Wagon.

I did the same at Brad T and installed the rear coil air bags. They worked great for a while and actually gave the rear a lift of about 2" when not towing. Unfortunately, a leak has developed somewhere and I haven't had time nor inclination to track it down yet.
