Don't look at dry weight as it is meaningless. Look at max trailer weight that falls within your capabilities. Work backwards from there figuring payload capacity minus whatever and whoever will be in the vehicle while traveling minus 15% of the max trailer weight on the tongue. Then subtract the 80 pounds for propane and 40 pounds for a battery and roughly 100 pounds for the hitch. You will come up with a very negative number if you start out with a 7900 pound max weight trailer. Work the numbers to find what weight trailer you can really tow.
