Until recently my 03 Journey DL 36LD with a 330 cat engine had averaged over 10 mpg for slightly over 10,000 miles. On our recent trip from GA to FL to Ontario and home, the mpg dropped to 8.2 mpg. We used the AC more than we did previously, but I have a hard time believing that the AC would decrease mileage by 2 mpg. We also pulled a toad this time so maybe that had an influence. Before we began this trip we had the RV serviced completely at the dealer's and we checked everything before leaving for Canada. Any ideas?? Would the combination of towing and using AC cause a 20% loss in fuel consumption?
Also, one of the house batteries failed and nearly burned up. We replaced the battery and consider ourselves lucky that the RV did not catch fire.
