We have the plastic factory Ford liner and because they had to cut it to put in the rails it now does not lay flat and junk gets under the liner. Not a great thing but we have a extang tonneau cover so at least it stays dry (when not towing). The in bed plug is in front of the left wheel. Being only 5'7" I have to use a step in order to plug it in. Also not the greatest thing but the odds of me growing are pretty remote so I guess I'll have to live with it
