30mpg with the Outback when not towing???? Seriously? You have gotten that? .... gezzz I never came close to seeing anything starting with a "3" on the gas milage computer on any of the 3 Outbacks I owned. 23 or 24 were common number & 17/18 around town .... and yup those are US gallon numbers due to being a US imported car. Subaru must have done some big time improving on their gas milage in later models.
Have not really noticed any additional issues with additional 2' in length with the truck and trailer combo - still get into small camping spots.... have notice the difference in finding parking for the truck on its own around town though
We have a ton of Outbacks in this area, and up until a few years ago, I heard the same complaint about not so good mpg on the Outback. But, most of the mpg complaints were the pre-2010 models that some of our friends had. Our 2014, even just driving 1/2 mile to work and back,(I should be walking to work!) really not even warming up the car, still gets 23. On the highway last winter we got almost 40 mpg when we had a relatively flat run at around 55 mph. At 75mph mpg goes down quite a bit. Still, when I go on an extended drive on the highway, over 30mpg is routine. The 2014 is rated 24/30mpg and that has proved accurate in our case. The 2015 bumped up to 25/33mpg, so I guess Subaru is working on improving mpg.
Right now I also have an F250 crew cab, 245" long, and it just barely fits it most parking spots and hangs out in others, so hopefully the 210-230" truck I plan on replacing the F250 with should be an improvement.
Thanks for the comments
