rexlion,
We've had both also, a 6 X 10 flat front with rounded corners 6' high inside for years and our present long pointed Vee nosed enclosed trailer 6' X 12' X 6' high inside plus the point length floor. Empty trailer, approx 200 lbs heavier than the flat nosed. Got a full honest 2 MPG better fuel mileage behind the very same 05 Chevy I-6 Trailblazer (275 hp-275 torque) with the Vee nosed trailer with the same approx. loads on the same trips up to our Son's retirement home 168 miles north. Both trailers were loaded on the way up and mostly empty on the way back. 3 trips with the flat front and 2 trips with the Vee nose.
Always drive on cruise control at 60 or under (retired and no need to tow fast and besides, the speed limit in Michigan is 60 mph max when towing a trailer on Interstates and 55 mph on non-Interstates). The roads are close to half interstate and 2 lane highway. US-31 in West Michigan from Grand Haven area to the Traverse City area. Direct comparison! Must be the way you are/were driving with a nearly flat front vs Vee nosed trailer not to have seen a difference. Rockets, jets, airplanes and most anything else going thru the air/wind employs aerodynamics for a reason! Even vehicles today and think about it? A 5,000 lb boat on a trailer pulls much easier on the throttle than a 5,000 lb travel trailer and guess why?
