I use to drive a 18 wheeler down through Orlando 2 to 3 times a week. Stick to the center lane and everything will be fine. If rush hour no worries you will just be going 5mph instead of 60. Like LOU said Steve you can do this.
I use therma cells. I have 2 of them and put one at each end of the camper. That works for us here is a link. http://www.walmart.com/ip/19206342?adid=22222222227014455821&wmlspartner=wlpa&wl0=&wl1=g&wl2=&wl3=13699875790&wl4=&wl5=pla
