George,
I get less than 14 mpg towing (12.8 on a recent trip to Florida and back to NY), but I think it has nearly everything to do with my heavy foot and not the WDH.
I bought my Ridgeline when they arrived at the dealerships one year ago. I bought the TM in June. I have only taken it on a couple trips and I am still learning myself. I think it's a great combination. But as I said earlier, it sounds like I could be wishing for more torque if I take it over any high elevation mountain passes.
I did have the 20 amp fuse in the line running to the DC Power to TM blow on me once. It happened on my way back from Cape Breton. My freezer food thawed but the fridge stayed cold enough that nothing spoiled. I have not figured out why the fuse blew. The Ridgeline comes with a spare fuse, but now I have a few with me and I open the fuse box to check the fuse once in a while while traveling.
Jim
