The cj with the dana 20 transfer case can safely be towed 4 down but that looks to be around an 82 or 83 and they have the dana 300. I modified my 300 by welding teeth on the shifting collar that is always turning while the drive shaft is rotating. What happens to a stock 300 is the gear oil doesn't circulate and the rear bearing burns up and seizes.
Traveling down I95 and had a small U-Haul truck with a very low rear tire in the lane to our right about 2 car lengths in front , the tire exploded just as we got up to it. Saw pieces flying wasn't sure if we got hit, but at the next rest stop found we had a 2 inch hole right thru the front cap just above the drivers side headlight. No we didn't any info off the truck. Still had the hole when we traded it in.
I left my gas cap sitting on the toads bumper and never got a code. Put aluminum foil over it till I got home 900 miles later. Didn't know what to buy for a replacement so went with a chevy 3500 with the 8.1 and it fit perfect.
We go to Fort Wilderness at Disney World quite often and use the route ferndaleflyer suggested (don't use 301 though). We stop at the KOA in Broadway Va. the first night, but I think we're going to try a walmart next april when we go again, and the KOA in Yassasee SC the 2nd night and hit the fort around 1pm . Avoiding the 95 corridor around the DC area will also save you a fortune in tolls. The cash you save will almost fill your fuel tank. We went to Cherry Hull Park campground in Colledge Park MD to visit Washington and the combined tolls for the MH and toad were $151.00. Thats round trip. Taking the other route was $14.00. Have safe trip. It might not be a bad idea to call any campground you might be considering for the first night just to make sure their open all year.
We use Yankee Candle fire starters. They are about the size of the average cupcake and are a wax candle that burns long enough for about anything to catch. Plus they really smell nice when you open up the compartment there stored in.
