Of course the best thing is to read the manual carefully.  I suspect that
some models of the Escape are towable four down without the need for a trans
pump, and some are not.   Here are a few of sites with flat towing info

Yes, you will need a braking system for the towed vehicle.   There are quite
a few to choose from.  I personally have a Brake Buddy, and it works fine
for me.

It sounds like you were possible thinking of towing the Escape on a car
hauler trailer.  Of course in that case,  you wouldn't need a brake system
on the Escape, but would  need a brake controller on the MH to operate the
trailer brakes.  I don't know what the Escape weighs, but that weight plus
the weight of the trailer, would probably exceed the towing capacity of the
MH.

You need to carefully calculate the combined gross vehicle weight.  That's a
fully loaded MH (fuel, fresh water, food & supplies, passengers), and the
weight of whatever you're towing.  If you're not sure what the fully loaded
rig weighs, take it to a public scale or truck stop, and have it weighed.

Also make sure your tires (MH & towed vehicle) are properly inflated to
manufacturer specifications....always check and set  when they're cold.

Does the 4-wheel drive Escape have a transfer box which can be put in
neutral?  If so, a trans pump wouldn't be necessary.
