I'm quite used to pulling a lightweight & low profile PS190. I was surprised to need to fill up once on my way from Norris to Cincy this weekend with a X1. I averaged just a hair over 10mpg, pulling with a Nissan Armada with a cargo box on top(some moderate hills and towing around 70mph). This ain't no hybrid and I don't expect it to get 30 mpg, but just want a gut check. Is 10mpg is normal?
It may impact my shopping choices when we look for a new tow vehicle this summer.
