First: Where did you buy your Ford? The Ford Dealer or an RV dealer, The RV dealer can suggest a service facility if they do not do it themselves.
I've had a few oil changes done on my chevy.
One at CW, they not only got it wrong (used wrong oil) they charged me too much.
Second at Authorized Workhorse Service/Chevy Dealer He had large bays and with the ground clearance, Who needs a hoist.
Rest at an RV dealer with a service dept.. Like the Chevy dealer, they use a crawler not a hoist.
You need not go to a Ford Dealer.. Just a reputable dealer or service center.
Heck, When I had a minor problem (Half my serp belt did some nasty things... Took me like 2 hours on my back under the rig to untangle it from the works) I pulled into a truck service faclicity on their oil change bay.. His techs took about 15 minutes to change the belt from that angle... They were very honest about it and the guy said he felt bad charging me half an hour's labor.
The whole job cost me about what a 1 hour minimum would have where I normally shop.
