Ridged and CJ3Flyr--just wanted to update you on my towing experiences so far with my 07 V6 and the new EDGE M21. As I said earlier the car has a frame mounted hitch and I'm using an Equalizer brand WDH. The trailer comes in at around 4K pounds including the hitch tongue, and the vehicle doesn't seem to be having too much trouble with it. I have been tempted to go for a V8 model in something, but the chart CJ3Flyr posted only showed a 600 pound difference in towing capacity between the 6 cyl. and the V8(did I read that right?). I haven't done any hill roads yet and I guess that's my concern--if I start up a large hill am I going to be slugging along at 30 mph uphill? Any comments would be appreciated.
