My feeling?
trailer is to long, too heavy and once again an EGO boost F150.
There are lots of folks who are drinking the EGO boost koolaid, I am not one of those.
That trailer is more in line for 3/4 ton or even 1 ton trucks.
Your F150 is going to labor pulling it and that 36ft length is a lot of billboard to pull behind. While your engine may have the power to move it, CONTROL may be the issue at hand. There is more to towing than the 1/4 mile, it comes down to how well the suspension of the vehicle handles a given load.
If you think the EGO boost is going to get 20+ MPG towing, forget about it, towing mileage drops to the same or less than say a 6.2 gas engine..
Its your money, your life, do as you will with it...
