If you plan to tow it with an RV consider keeping your stock wheels and tires just as they are for towing and get a set of 30" mud terrains on 15X7 steel wheels and keep them on the roof of the RV till you get to a serious trail destination and then switch out. That would save wear on the big tires.
Also I couldn't tell from the pics if you have them but manual front lockouts are a real plus also. If you have auto hubs you may want to switch to manuals. I have read that it is real important to have manual lockouts for towing. I believe it is a real simple and cheap switch out for under $100? If you are interested in that there have been a number of posts on that topic.
I have talked to a number of RV'rs who tow Track/kicks and they say they pull real easy and are so light and compact that they don't effect the milleage etc. They seem to be the preferred tow vehicle. Add the 4WD capability and man what a versatle combo!
