I will be driving interstate the whole time (80 mph) and the car will be loaded up with driver plus three people and a bunch of camping gear (maybe 1000lbs total of gear and passengers). Does anybody have experience with doing something like this and want to share their fuel economy figures?
Also, I may be putting on one of those trailer hitch cargo platforms on the back for more storage space. Anybody have any experience with those and how they effect ride quality/fuel economy/noise/etc?
Any feedback would be amazing! Thanks!
My only experience with an enclosed roof top carrier is as follows: I'll never do it again! Yes it does cost mpg (wind drag)and it also increases wind sway. That is from gusts and/or passing trucks.
A rear platform would be better. With that weight and 80mph I'd be very careful. But again that's my personal opinion.
Actually once I got a pop up camper with extra wide HD tires I could eliminate the car topper. Found it much easier on the highway.
Actually you might be better off with a small utility trailer w/ wider tires, depending on how many of those trips you take. It will be easier on you and the vehicle. But again you will not be able to do 80 mph.
Just a thought.
