I am starting to see the advantage of class C's but I really don't care for the look of the cab over.
Like spark plugs! LOL Changing out the spark plugs on any V-10 application is difficult. On the F-Series the passenger rear two plugs are a pain in the #*$% to get to. The E-Series has its own challenges.
From what I saw, however, when I had the doghouse off: If the shop can get the Axis/Vegas up on a lift getting to the plugs from underneath looked like a viable option.
Note how low the engine sits in the following picture:
The spark plugs are well below floor level. I haven't crawled underneath to verify this though.
The pic does show how much work it would be to remove the engine.
