Mileage loss with trailer
Recently completed a trip with a trailer. First time ever with a trailer. Experienced a significant drop in mileage, about 10 to 15 mpg drop. Depending on wind. My questions are 1. is this about the norm? 2. It is not streamlined just a flat bed with a big tub on it, does streamlining help? 3. Does the speed I'm driving have a significant impact? any info is great as I've never pulled a trailer before. Thanks Dan

Re: Mileage loss with trailer
I have a clamshell trailer and it drops me between 8 to 12mph. Speed affects it more than anything but drag if you tie things on it can definitely drop your mileage. I put a wheelbarrow on it and my usual of 45mpg (no trailer), 35mpg (w/trailer) dropped to 28mpg (weight was high and a lot of drag on the freeway). Drag affects more at speed and weight more in the hills.dcmrn1959 wrote:Recently completed a trip with a trailer. First time ever with a trailer.

Here in the west, because of long distance between gas, I carry 3/4g (1 gallon can, with space for expansion) of gas mounted on the back bumper of the trailer. I started doing this when I didn't have a working reserve light and twice showed only 2/10 of a gallon left (filled 5.9g). It works now (replaced sender this winter). I have yet to add to my bike from it, but I have done so on the last trip to my wifes bike as she gets from 160 to 190m on a tank (4g tank, 55mpg) but we don't ever try to get that close.
Her bike started acting like it was out of gas and when we checked she still had 2 gallons left.
Reading forums, I think her vent in her cap wasn't working. I just cleaned it so hope that is fixed now.
Enjoy your trailer. I prefer to travel without it as I enjoy the bike more, but I take too much along for more than a weekender, so I take it for longer trips. Plus out here in the west we encounter such varied conditions that we take 2 helmets each (1/2 and a full face) and I usually take a guitar along.

Re: Mileage loss with trailer
I used to have bad mileage until I redone the suspension on our trailer and could run the higher tire pressure. now its only about 180 miles to the empty mark instead of 200 miles. I can live with losing just 20miles per tankful pulling a trailer. I ran out to Page AZ. to pick up my wife at that airport in four days at superslab speeds of 75~85mph the whole way. The faster you go will drop your MPG but tire pressure will also affect it. If your suspension can handle the roads with the recommeded air pres in the tires the better off the MPG will get.

Re: Mileage loss with trailer
With our triked Voyager we will get 35 to 38 MPG riding two up. We have an all aluminum Mini Trailer that the title weight empty is 200# according to the manufacturer. Do not consider that too bad since the Voyager now weighs 1000# by itself.

Been a while. This is from my trip to Washington state then on to Colorado Springs, CO. This was the morning Harley and I left for home (last week in April 2012) with my wheelbarrow my brother-in-law had borrowed.
I would have thought it was more aerodynamic with its upside down wing like shape.

Re: Mileage loss with trailer
Gene hit a key point. If you get 45 or + at about 70 mph, don't think you will get that with a trailer on. Drop your cruising speed down about 5 mph and your mpg loss will be minimized.
I used to get about 45 on my '94 with two up and no trailer. With my Aspen Classic camper it would drop to about 33mpg. If I tried to maintain a 70-75 mph speed, it could drop to 25mpg. So back off the speed and you will keep some more of your mpg.

Re: Mileage loss with trailer
By the way kjsett how did you train Harley to ride? Im looking for a dog and was wondering how I would train it. Dan

Trained, not really, he rides in a dog bag on the faux tank. Unfortunately he is now pushing 17 and doesn't like being cooped up in the bag that well anymore.dcmrn1959 wrote:By the way kjsett how did you train Harley to ride? Im looking for a dog and was wondering how I would train it. Dan
I saw a bag that was like a sissy bar mount behind the driver. Don't know what brand, but I think if you aren't riding 2 up that it would give the dog more room.
Just have to search on line for one. Motorcycle Dog Carrier turned up a few, here's one example:

Mine was less expensive:

except mine is orange and grey. You have to buy the motorcycle tank pad connector and I also added the rain cover. You can see it just in front of me on the tank in the picture.
Make sure you get one with more than extra room. If you travel long distances like i do, he/she needs a little extra. Most of the time he travels with his head out so we also got him a pair of "Doggles" for his eyes (he doesn't like them, but they are sunglasses basically).
Young dog will adapt best, but I wouldn't try it with a puppy.
Enjoy

Re: Mileage loss with trailer
Hello Ken, Looking at your pic, I see you have alot of safety chain hanging. My concern with that would be that with so much chain, if your hitch did ever come off , the nose could drop to the pavement, and second , trying to stop after it came off the darn thing would have enough chain to come up onto your rear tire. Causing even more problems. I have had several people show me the right and safe way to safty chain the trailer in a criss-cross fashion with enough slack to make full turns and being crossed , too cradle the hitch and not let it drop to the road or have enough to get up to the rear tire. Hope some more will chime in with this issue. Gene and Marie Kap.

Re: Mileage loss with trailer
Thanks for all of the posts
I've been pulling a Time Out Trailer since 2005, the Time Out has been to every rally since. When I had my 1200 Voyager I just kept the speedo at 65 mph, but MPG was 40. With the new 1700 Voyager, on the way to Kanab last year I tried 70 mph and wow, 30 mpg. Slowed to 65 mph and the MPG came up to 35. The good thing about the slower speed is that Tire life is much better.

Re: Mileage loss with trailer
Probably a little late to help much, but I've been pulling a ASpen Sentry for a couple of years. Certainly the weight has much to do with mileage. How it's loaded, balanced, tire pressure, the whole smash. I've had as little as 28 mpg and up to 42 mpg. Weight was a big factor. I dragged the camper in cross winds with 35 mph sustained speeds and gusts up to 45 mph.
Worst mileage was riding 2 up with the camper overloaded. Best mileage was open highway, 1 up, with the camper minimally loaded.
Aspen weighs in at about 350 lbs empty. Loaded add another 100 lbs. Loaded with wife's stuff, add another 100 lbs. That's a lot to haul.
I am looking to sell the Aspen just for weight savings and go old school. Back to a tent (albeit a cabin tent) but after figuring all the weights of the equipment and minimal supplies, I can cut the towed weight down by almost half.
So, if anyone know of someone looking, It's in the classified section.
