look in the user manual for fuel shutoff switch which might be activated by towing. Normally this is only activated in an accident...

Im not positive, but dont they have a switch in the glovebox? That is turned off for towing?

You can tow your MKX behind your motor home. I've been doing it for years. Your owners manual tells you how to do it. You must tow it by all wheels up or all wheels down. You can not use a tow dolly. Make certain that you get a good tow bar system and have it installed. It took them a day to install mine. But I feel safe towing it.
Have fun RVing.

Not for more than 5 or 10 miles.

Not if the pump seal is good

It shouldn't drain down overnight either

If it is AUTOMIATIC then NO
for a MANUAL /STANDARD gearbox then YES

Automatic can be towed so long as the driving wheels are off the ground

for 4wd and 4x4 there are different aspect to consider

you must use a car hauler/trailer.

The 2007 Lincoln MKX is definitely towable "4 down". According to the owners manual: The ignition switch needs to be in the accessory position (position 2 of the 4 possible positions) so that the steering wheel is able to turn to let the front wheels track the towing vehicle. The transmission needs to be in "N" so that the engine's disconnected. The parking brake needs to be off, and the engine should be run for 5 minutes before starting out and "at fuel stops". This makes the vehicle a good vehicle to tow along with you behind your motorhome. The folks at Blue Ox make an excellent tow "baseplate" that is practically invisible yet hooks up easily to the motorhome. The BX2192 package is made specifically for the '07 to '10 MKX. It works beautifully with my '07!

who towed it was there a towing sequence eg take a fuse out ect like some other cars
