Does anybody have any MPG numbers. We are planning a 1,800 mile trip from south Florida to Tennessee. We hope to get 12 - 13 MPG. This will be our first trip with the Vibe, getting excited can't wait to get away. We weighed our trailer empty except for full bottle of propane and it weighed about 3,100 lbs. with a tongue weight of about 360 lbs. We are going to try to use our equalizer WDH rated at 4,000 lbs. which we kept when we sold our r-pod. I think in time we will need to upgrade to a 6,000 lb. WDH.
