Ideas? How to make a CJ aerodynamic while on the trailer?

Ive been trying to devise a plan, something to bridge from the hood to the windshield in efforts to deflect some wind off the cj for my upcoming 2000 mile trailer haul.. may be good for 1-2 mpg along the way, plus i can feel the blast of every semi truck that goes by right now and would like to ease that stress on my straps.

A piece of plywood is my best thought so far but cant decide how to attach it..

A) Your straps are not troubled by air flow.
B) The air dam is your tow rig not the cargo.
C) It sounds as though your tow rig is a little light for the job, if it is getting sucked toward the passing semi's. you might try a little more tongue weight or load some stuff in the bed.
D) There is a low pressure zone on the hood of the CJ I would bet. Created by the turbulence from your tow rig, so you aren't saving anything like 1-2mpg. Put some streamers on the CJ and run it up to highway speed and see which way they blow.

Here you can see my concern, the tow rig is plenty heavy and has a tow rating of 11k, however the jeep sits much higher than the plane of the truck and without doing the streamer test ill bet that windshield catches some serious air.

It looks like you might need a little tongue weight.

The obvious would to be just fold the windshield down.

Lol I have never had any problems trailering my cj7 or any other jeep for that matter. I would say try a full cover on the jeep see if that helps especially if your planning a long distance tow

Get one of those big wind deflectors off the top of a tractor trailer and put it on the hood of the Jeep. 😊
