I do a lot of my own repairs and have owned both side and rear radiators, at 74 years old I would choose side radiators every time, rear is OK but I am not as flexible as I used to be.

I hear you. Not quite at 74 yet but doing the slinky under there working around my rear PITA radiator has me at a point where I pop a few Advil, make a cup of coffee, wait 20 minutes and THEN go under there.

I agree w your conclusion and most of the points you mention. I wonder about your #5 however...
Where does the energy come from to run the hydraulic pump? Doesn't it come from the engine... there really is no "free" energy and I think you pointed out the SRs actually need more cooling than RRs.
I don't know the details but will guess more HP read to cool larger SR engines?
What am I missing / ovetlooking?

Nothing. The laws of physics still apply.

That's true, but the hyd pump is still necessary for the steering, so if fan doesn't have to run at high speed to cool radiator, less hp is required by the engine to run the pump.

I'd bet that Newell will have a side radiator.
I don't know about others, but I would expect it. Look at any line of diesel powered coaches and the lower priced models have rear radiators and some where up the model line up they switch to side radiators. I know it's not HP related because you can find the same engines in rear and side radiator configuration.

Agree in the lower powered, smaller displacement small to medium size engines.
But as I mentioned, the bigger displacement, ISX, ISM, C-12, 13, 15. Series 60 engines, even in lower line coaches had side radiators. On the other side, even the cheapest model, smallest engine Foretravels and most Country Coaches had side radiators. Go figure.

You are correct, on my 96 Monaco Windsor, the stock fan is powered by the same pump that powers the power steering! But the PO put two big electric fans on the outside of the stack blowing cool air in from the out side, and they do a great job! I have never heard the Hyd. fan kick on one time in the four years I have owned it, been all over the east coast mountains and the west coast in the summer and have never heard it kick on, and the temp. gauge is steady as a rock, running at 190*!
Also, my Windsor has a 8.3 mechanical Cummins and has the side radiator!
I think the electric fans are the future, as in the 2020 Prevost! Rail!

Totally agree, many hyd fans are low and high speed only, and many direct drive fans the same. But with electric, one fan at 180, two fans at 182, three at 185 etc. Need a good size alternator, but think would still be way more efficient than hyd or direct drive.

Except mine that is :-)

Yours isn't a lightweight coach and also falls under the definition of higher end coach in the original Monaco lineup. So for both reasons, your coach got a side radiator. HR Sceptor and Monaco Camelot were the starting points for side radiators in the Monaco lineup.

99% of all Country Coaches had the side radiators even down to the 32' with one exception. In 07 they made the Tribute with a rear radiator but it had a short life.
I do all my own service so a side radiator was a must, love it.

One might ask themselves, as to where does a manufacture spend the money, after the WOW factors are put in and every other quality feature that they can think of is installed for attracting only the discriminating buyer.
Answer....An upgraded chassis with the side radiator, so all one needs doing when looking for a quality unit, is to go look in the rear, firstly and foremost.
