Love the Seneca, but wish it had a little more power. It did well on the trip though from OKC to Albuquerque. Got about 7 MPG towing while having the cruise set to 74. I was in a hurry to get back though due to easter. Normally while towing like this, I would be in the 65-70 MPH range and could easily get another MPG out of it. When empty, I can get about 11 out of it. It did slow down while pulling grades, down to about 55 MPH, but for only having a 340 HP motor, I think that is pretty darn good for towing. Dynamax makes the Force HD which is basically the same thing, but offers a 8.9L motor instead of this 6.7. But your looking at like 40K more in price point, which I was not ready to do. That and there are far more Jayco dealers than Dynamax dealers out there to offer support. I had to laugh because it was not planned at all that the truck matches the Seneca.
