i've already measured and it will fit inside, my three wheeler is long and low

To answer a question with a question, how does your highway FE compare with ATV in the bed versus box empty? That seems like a prudent starting point for your particular situation.

We "might" help with interpretation of field test data but be careful about thinking somebody else's ideal solution will work for your truck just the same. That's a sucker bet.
mid 30's WITH the three wheeler in the back, high 30's without it as there is no room in my garage i just keep it locked in the back of my truck most of the time and really don't notice that big a difference but i drive very slow 55-60 at all times on the highway hugging the right lane and 95% of my road time is highway - i think i'll take "3-wheelers" advice and try out the cap and report my findings-
thanks for the help everyone!
