My 78 Royale has a single original Duo-Term 13.5k BTU roof A/C that is working well. However, I live in Florida and plan on camping during the summer (think 95+ degree days). I don’t think the 13.5k will handle one of these very hot days (I like it nice and chilly inside). Here are two options I’m considering:

- replace the original 13.5k with a 15k Coleman Mach 10 (I love having the digital control and Bluetooth);

Or

- keep the original 13.5k and add a second unit. In this case I’d go with the 13.5k Mach 10 NDQ (quiet version). I’d run the latter primarily and in a very hot day I’d use the old Duo-Therm as a second unit. Another benefit is the redundancy (if one breaks down during a trip, I still have the other :)

I really like the quietness of the NDQ, but at 13.5k it may require a second unit on a hot day.

My questions: do you guys think a single 15k unit can handle 95+ degree days? Also, will the 30 AMP shore line be able to handle two 13.5k units running simultaneously?

Thanks!

Get rid of the ol 13.5 and put 2 new 15kbtu units in. Be sure your
generator is reliable. Beef up insulation where you can. Tint windows and
use white reflective paint on the roof (and sides if possible). Inatall
full length awnings on both sides.

Like I mentioned earlier in this thread, it is like 5 blind guys looking at
an elephant. One has the tail, one a tusk, one a trunk, etc. NONE OF THEM
REALLY KNOWS WHAT THE WHOLE CRITTER LOOKS LIKE. Same with various years of
GMC coaches.
Only reason I have a fair idea of them, is i have worked on so many
different year models. Believe you me when I say some of those changes are
hazards to navigation.
Same can be said for R.V. park service posts. UNTIL YOU CHECK FOR
YOURSELF WITH AN ACCURATE METER, YOU NEVER KNOW FOR SURE WHAT IS WHAT. I
personally have found 3 phase 240 volt service at those posts. That will
wreck your day for sure if you jury rig into that.

Oops! I missed that it is a Royale which only has 30a wiring. However, it
has still been done successfully. With another 20a circuit on its own
cord. Just plug into the 20a receptacle right by the 30a on the same pole,
usually.
