aerodynamics & 5th wheels

Hey all,

OK, so came here looking for VG designs, now have way more questions...

I'm starting with a 2012 ram 1500 (quad cab, 140.5" wb), towing a 19' frontier 5th (3000lbs - just a baby not a monster 5'er) I'd love to post pics of the pair, but... well I'll leave that alone for now manufacturing defect hopefully get it back later this week)

Any who, wanted VGs for stability - as we spend our vacations running the rogers and crowsnest passes - side winds and passing trucks are a major issue, but researching placement etc, realized that's not my biggest issue... leaning towards a couple strakes on the roof + VGs on the sides. But now, what to do about the mess that'll be created between the cab and 5th...

Roof line of the 5th is only about 2' taller than the truck, deflector can be added easily, but with my 1 tow with the pair - I literally had tool boxes flying in the bed (yes with tailgate up) 5th has a v shaped nose, so I'm guessing its pushing a fair bit of air down into the bed of the truck...

Shot of the 5th:
<snip - guess I need more posts first>

Any thoughts on how to make the pair a little more fuel efficient?

Thanks in advance!

Andy
