Thanks-
A rule of thumb that works -- be it 1973 or 2013 -- is that towing will decrease highway mighelage by from 30-40% from solo. Much is dependent on the rig (how well the vehicles are spec'd in re fuel economy), and then climate, terrain and driver use/skill enter in.

When compariing vehicles -- and an Airstream is the TT in question -- then use the EPA Average mpg as a starting point (for non-mountainous terrain).

Someone who wishes to keep fuel burn to a minimum has first a trip plan of how to minimize the amount of engine hours time between two geographical points, and then works to drive those miles with the highest skill possible.

Keep records of all miles travelled / fuel consumed. The mpg average is what counts. Convert that to cpm (fuel cost as cents-per-mile) for predictive purposes (as in my signature).

For me, a 1,000-mile trip on generally level Interstate will cost 25-cpm where diesel averages $4/gl. Or, $250.

It depends on the tow vehicle and the driver's habits, the roads, the weather, etc.

For example, this last weekend, towing on relatively flat land, I got roughly 11.5 MPG with our diesel truck while towing the camper. That included a number of traffic lights and all, too, so not all highway. With the camper on the highway, I can hit ~12 MPG.

But I get about 11 MPG when I'm driving the truck around town solo, with a lot of traffic lights, stop signs, etc. Like any vehicle, the stops and starts really kill the mileage. On the other hand I achieved over 17 MPG solo on the highways with the truck, even with climbing mountains on the PA Turnpike and I-70. I got roughly 13 MPG while towing a U-Haul trailer with a car on it over those same roads in the other direction, so that matches the 4 MPG that person reported.

The point of the numbers above isn't really about the mileage itself, but the comparison between towing mileage and solo mileage.

But, in general, fuel costs are a huge component of usage. Not ownership as much - if I never used the camper, I'd never pay for any fuel to move it - but it does have to be figured into the costs of a trip. I think I spent about $600 one way for a trip from DC to Disney World in January, 2012. To me, though, that wouldn't qualify as a "hidden" cost - it's pretty obvious that moving several extra thousand pounds around is going to cost more. From a strict cost point of view, it might have been cheaper to fly and stay in a hotel there, but that's not what we wanted to do.

My financial data wasn't really difficult to keep. I use Quicken in which all of my transactions flow in automagicly so I know where my money is going; can't do much about it, but at least I know where it's going. I am somewhat anally retentive in keeping up with my cash transactions, but we all have our faults. Anyway, all I had to do was pull a report in Quicken and convert it for upload.
