I remember that one of the most important parameters guiding our choice of a first (and only) diesel coach was it had to have a side radiator so that I and hired mechanics could easily access the engine. Being raised on a farm, the first rear radiators I saw left me scratching my head over how anyone could work on such an animal without some consternation at times. And as a potential purchaser I wanted to have more than just a bare glimpse, without crawling underneath, of the engine I might be buying into. Plus I'd begun hearing about bypass oil spray and dirt mucking them up.
Each time we were attracted to a coach, as soon as I saw a rear radiator, we just walked on to the next one. I soon learned which models had what, and saved a lot of time on dealer lots and ad perusals. It was one of the things that turned us away from the Winn. Journeys, the rigs we researched first some 15 or more years ago.
At least you have fellow owners and experienced help here as a resource, D. Whenever you have a specific access issue, if there's a best way to expedite things, it's likely someone here knows what it is - just ask.
