I own a 1999 Wrangler that is a hobby and the wife and I enjoy crusing around in it. We have a travel trailer that we tow with a Ford F250. We would like to be able to tow our travel trailer with a wrangler unlimited 4- door. The GVW of the travel trailer is 7000 lb. Can someone tell me if there is a set up available that would allow me to do this ?
