Hey Narian,
I asked a similar question the other day. You might want to take a look at " which A/S can I tow with my jeep gc" (some one might be able to show you the link) I don't know how..
I am really suprised what my Jeep can tow safely. We started looking at 22' and with the advice of many others are now only looking in the 19' range. The more I read about my jeep the more I think that jeep over estimates the tow ability (IMHO)
Good luck with your information gathering!!!!
