Suspension mods to lower height of TT
I have a 2013 Keystone 19FBPR TT that Keystone chose to stick way up in the air. Not sure what their intention was by doing so, but it causes this small TT to tow like a 35 footer. I won't say th...

3-4" lower won't do diddle for mpg's IMO. Look around at all the TT's being pulled on the road. Almost everyone is a different height. Then read about towing and mpg's. It's always the same range for gassers. Your 250-6.2 isn't shy about going to a gas station.
Granted the F250 doesn't have any issues not passing a service station. As far as mileage goes, neither was the F150 5.4. But, a 12 foot 6 inch sale is harder to move through the wind than an 11 foot six version of the same sale. We could go into formulas for drag coefficient and come up with some nice numbers too. All of this should have been done at the factory. But, the factory chose to use whatever was on hand and stick the unit way up in the wild blue yonder.
By the way, I wonder why the people pulling fivers will put wind deflectors on their tow vehicles? Might it be for the same reason I want to lower this one? Thanks for your comment though.
I'm sure lowering it some will help, but 3-4" is a far cry from 1'.
FWIW I towed a 31'OAL 11'9" tall TT with a 2010 F150 5.4 3.73. Averaged 8.5-9mpg. Traded up to a 12 Ram 2500 CTD 3.73. Got 10.5+ with the same TT.
Now have a 28' 12'6"H 5'er and get 10.5-11.9mpg. The 5'er is a mid profile front. Taller but more aerodynamic. JMHO but lowering your TT a few inches probably won't register enough to really matter.
No harm in trying though.
On the wind deflectors. I've only seen a few in my travels. If they really made a difference then more RVers would have them. My guess is the cost of installing one and the gains in mpg are too far apart.
