My motorhome is a 2012, but the chassis and engine are a 2011 E-450, which is slightly different than the E-350, but then again my motorhome is 32' long, so it is bigger and heavier than what you are looking at. That happens when the chassis is delivered during the summer, just before the new models begin to be constructed, so it is pretty normal. One thing that amazed me was that my first big trip was across Wisconsin, Nebraska, and Wyoming in 100 degree temps in early July in 2012. In addition, that route constantly climbs, sometimes slowly and sometimes more steeply. I was convinced that my temperature gage was broken because it never budged off of the center! In fact, no matter how steep the road in mountains, and I have done a lot of mountain driving, it has never budged from the center. I am told that is due not only to the engine but to the cooling system, since I have a super heavy-duty cooling system. So, you might want to check what kind of a cooling system yours has.
I have worked for both GM and Ford at corporate levels writing training material and been in a lot of plants, and in terms of trucks, Ford has the better reputation, which is one of the reasons I made sure I got a motorhome with that v10 engine on a Ford chassis. I was also told by Ford engineers that that engine ought to be good for 200,000 - 300,000 miles with no problems. Consider that the vast majority of those engines are put in medium-duty delivery and commercial trucks, so they get a lot of hard use by people who don't own them.
If the engine bolts are a problem, perhaps your mechanic friends can just check them more often.
