it takes spark fuel and compression to make a engine run. you said fuel pressure was good. start with spark is it good if no spark check all fuses.I have seen wire rub on the frame and blow the coil fuse.
Well, I just won the newbie mechanic of the year award.
After making arrangements to have the RV towed to my mechanic, I decided to check the fuses one more time, after reading your post. I noticed that the fuse for the Body Control Module (BCM) was missing. I also noticed that a fuse with the same amperage rating was in a slot that was designed "spare" (e.g. a slot should have been empty.) I moved the fuse from the spare slot to the BCM slot. The RV started without a hitch.
When I initially noticed that the engine would not start, I checked all the fuses, before I did anything else. I am sure I moved the BCM fuse to the incorrect slot when I did so. We then proceeded to replace the various components that are mentioned in my original post. The fuse was in the BCM slot when the problem surfaced, so clearly, one of the components we replaced was the culprit. However, whenever the original problem was fixed, the engine would not start, because BCM was not receiving any power. Long story short, we have no way of knowing what originally caused the problem.
Thank you to everyone who provided input!
