Congratulations! You may want to check out the Legacy forum as I think a lot of things on there could be applied to your MH also. I had a little concern with the 340 HP, too, due to a salesman at one dealership telling me if we were towing anything we needed the 360 HP engine. The only difference I've seen is the 340 comes with a 5K hitch and the 360 has a 10K hitch. Towed our Jeep from Orlando to Smoky Mountains and didn't even know it was back there, including going up and down the mountains! Enjoy!
