Travel trailer "vs" fith wheel --MPG to tow
How much difference in fuel MPG`S have you had with a bumper pull compared to the large wind resistance of a fiver? I have noticed a high fuel consumption in a head wind. Is it streamlining or lack ...

Dont assume just because its taller a 5er has more air resistance than a TT.
5er and TV act like a single large mass cutting through the air while TT and TV act like two separate masses with a lot of dirty air in between.
I would like to see any air flow pattern studies showing this. especially if the TT is roughly the same height as the TV.

I have felt this. Back when we had our 29' TT, some times I would pull with a cap on the truck, sometimes without. It pulled noticeably harder when the cap was off the truck.

I've always wondered about that... I have high cap on my F250 (high enough for me to walk in the bed just slouching a bit). When we first got the truck, I towed for a couple years without a cap. It has been 6ish years now with the cap... I don't really remember if there has been a big fuel difference.
Actually, since I don't remember a big difference, I don't think there has been one. I've always kept track of my fuel mileage using a calculator. On a lighter note, my F250's "fuel computer" consistently says I am getting 1/2 gallon better fuel mileage than what I figure by calculator - I have no idea what this means! lol
