Update (and resolution to this): Well, the guy I'd been working with on this (Mark) came out today, and replaced the broken fuel line, and the broken wire for that one coil.
The part he got from Ford was one large assembly going from behind the engine all the way up to both fuel rails on either side of the engine. Sooo, it is now all new fuel lines going from about middle of the transmission all the way up to the two fuel rails.
He also looked everything else over, and found no other evidence anywhere, of any damage.
Engine runs like brand new again, we are back in business (although not planning any trips for a while). No more smell of fuel, either.
Very impressed with the work he did, how knowledgeable he was, and how reasonable he was $$ wise with this. If anyone near the Denver, NC area needs any kind of RV related work, you can trust this guy, give him a call - Mark Hammill, 704-635-3265 (Yes, I got his permission to post this). He apparently does RV coach work as well, not just chassis.
I got some rodent repellant spray, and sprayed it very liberally on the ground, all the way around the perimeter of the RV. That, and will also make it a point, especially in these cold months, to exercise the RV more and get it out more often so critters have less chances to mess with it. I had been doing such about once a month, but due to the craziness around Christmas, it had not been exercised in about 2 months. I think that's one of the main lessons learned here - We really, really need to get these things out and exercise them at least once a month, for numerous reasons.
