Sadly many trailer sales people will tell you your current vehicle will tow their trailer just fine and vehicle sales people will say people tow with these all the time

Your own research and safety threshold plus factoring in the safety of other people on the road are what you need to look at. I read an article the other day that 800 people a year are killed in the US from improper hitching. One of the things that bothers me about our Scamp is the lack of a safety breakaway switch on it.. Standard on our Casita.
=====================================
Can you provide a reference for that 800 fatalities figure for future reference? The last time I saw a number that high was from a company that was trying to sell their "Safe" hitch and claimed that trailer hitches came disconnected "All the time" Thanks

We've had two tow vehicles, a 2004 Honda CRV, 4 cylinder, manual transmission towing 3 different trailers, a Sunline 15.5, a Casita 16 and our Scamp 16, all over North America, 250,000 miles.

Presently we tow with a 2014 Honda Odyssey, automatic, V-6 towing our Scamp 16, only 21,000 miles.

Like Bob, I find the 800 fatalities per year to be very suspicious. On average that represents 16 per state and in 30 years I've never heard of a death here let alone 480 over that period.

We towed for many years with our Acura TL 6 cyl automatic. We had a brake controller installed along with the hitch fitted for us by Can Am in the London, Ont. area. Absolutely terrific drive. No problems with power on uphill climbs. But...that vehicle is now 14 years old....and it was time to upgrade.
So, last month we picked up a 2008 Toyota Highlander. V6, automatic. It has a higher tow rating. Figured that was a good idea. We haven't yet towed it further than 100 kms from home to our recreational lot but it pulled it effortlessly.

I have a couple of friends with big diesel Chevrolet pickups that get over 25 mpg on the road - they tow 28' car trailers with them and still get over 20 mpg. A fiberglass trailer would be barely noticed and probably only demand a 1-2 mpg penalty. Another friend had a late model full size gasoline powered Chevy that would get over 22 mpg on the road. Big lazy engines turning 1800 rpm in sixth gear can get great mileage and be supremely comfortable. Even if you have to pay a mileage penalty of $100/year the added safety and comfort of a bigger tow rig may be money well spent.

I pull my trailer with a 2007 Land Rover LR3 - forty years of driving Land Rovers in all conditions have convinced me that full time 4WD is a valuable safety attribute that I am willing to spend a little extra money for. I bought the car used two years ago for $16,500 (new cost was over $54,000) and it is a delight to travel in. I get around 19 mpg on the road towing a 1500 lb trailer.

That claimed "Over 22 MPG" may be pushing it a bit. Here is a link to the epa's figures and also to typical user reported figures for each.


Note that each takes a huge hit on city MPG's, a stiff price to pay unless you spend all of your time not towing and on the hiway.

Spot on Bob.

And, even a lighter, smaller fiberglass trailer has frontal area, and that frontal area produces drag and has a dramatic effect on gas mileage. If a Silverado "typically" gets 25 highway not towing, a "typical" result would be 16-17 mpg max when towing, and that includes a small fiberglass RV.

We have a pretty economical setup with an F150 2.7L Ecoboost towing a 3200 lb Escape 19, but we do take about a 9 mpg hit when towing - not mainly because of weight, but because of the additional wind resistance from the large frontal area. Ironically, a larger and heavier trailer would produce similar results with our tow.

Robert,

You mentioned a 9 mpg hit when towing.

Could I ask what your in-town, highway, and towing mpg numbers are and what your towing speed typically is?

For our 2014 Ford Escape 2.0L Ecoboost FWD, we are getting 32-34 on the highway,
about 23 mpg towing a Scamp13 at ~60 mph, and ~24-25 mpg in town.

I have considered an F-150 2.7L Ecoboost whenever we upgrade our other car.

Also, about how many miles do you have on your F-150 and how has your reliability been?

Just curious .... 😉

Ray

I have a 2014 F150, 5.0L V8. Get 21 MPG around the neighborhood, 23 MPG highway when not towing. Plan to use this when towing a 13 or 16 ft Scamp or Casita in the fairly near future. I've also been looking at caps for the truck bed. A.R.E. advertise that their wedge shaped caps (higher at the rear) act as a wind deflector when towing a trailer, directing the wind up and over the trailer, and thus improve MPG.

Anyone have any thoughts on this aspect of a cap?

Lyle, a number of folks here that tow with a van or minivan say those vehicles punch a hole in the wind and probably keep the MPGs up. Your idea of that type of cap can do nothing but help deflect the wind over the trailer. Look at how many semi's have a deflector on the cab . Must work. But really, if you're going to get into RVs, it's going to cost you a few extra bucks to play.

Lyle,

I would like to find a good air deflector for our Ford Escape or, maybe
better yet, a deflector that might mount on the front post/jack of the
trailer to deflect air up and over the trailer.


The other possible issue is the fairly large flat plate area at the rear
of the trailer (that is why the little teardrop trailers have such low drag).

They say that sometimes a picture is worth a thousand words. You
could take a look at these pix:

That Airstream chart is actually from a very old Airstream advertisement and is nothing more than advertising. There has never been any additional information found about which vehicles and trailers were used, how the tests were performed and who "Dr Buckley", at U of M might be. But, it's on the internet, so therefore; a) it will live on forever and b) it must be true.

I've been a licensed pilot since I was 16 years old and have always had
an interest in how aerodynamic drag contributes to reducing the speed
of airplanes.

Whether it is on Airstream trailers or some of the FGRVs (Scamp, Casita,
etc.), rounded corners and aerodynamic shapes do count for something
in terms of drag reduction and increased/decreased MPG.

The predecessor to the Airstream trailer was the Bowlus Road Chief
that was designed by the same fellow who designed the "Spirit of St. Louis"
airplane. (There was actually a Bowlus Road Chief at the Oshkosh air show
this year. You'll notice that the Road Chief actually has a teardrop-shaped
back end.)

There have been several references on the forum citing the extreme
importance of the "frontal area" of a trailer as being the primary source
of aerodynamic drag. I believe that concept is only partially true.

The wire and airfoil picture is from an article call "The Zen of Drag Reduction",
by Barnaby Wainfan, that appeared in the "Wind Tunnel" column
of "Kitplanes" magazine in June 2013. I have the whole article
but have not posted it due to concern about intellectual property rights.
(Barnaby was at Oshkosh again this year and I have personally spoken
with him on several occasions.)


Regards,

Ray

We tow a 2012 15' Parkliner with a 2014 Ford Escape with the 3500# tow package. We look to sell the Parkliner (and the Escape) down the road a couple years and upgrade to an Escape 21 or 5.0TA. We've been looking at Nissan Frontiers for that duty. With a V6, even with 4WD, they will tow 6300#s. We're hoping mpg figures improve industry wide over the next 2 or 3 years, and maybe we'll all have better choices!
