AC size for 19' Shamrock?

[shamrockMennonite]

Just purchased a 2004 Shamrock 19', for which the previous owner never had AC for. I want to add one, and with that have a few questions if I may.

For those that have AC on a similar size hybrid, what btu size unit is on your RV's? I've been thinking of either an 11000, or 13500 unit. Any comments on either of those as to best size for the trailer I have?

Trailer is 'AC ready', with wiring running up to the roof vent. Other than buying the AC unit, and a non ducted ceiling shroud, is there anything else I should be considering? As for installation I have the capabilities of doing that myself.

Or, has anyone ever cosidered other options instead of a roof AC? Portable AC unit perhaps?

Thanks in advance for the opinions and suggestions.
Gord.

standard in the Roo/Shamrock, is the 13.5k a/c.

very, very few Roo/Shamrock owners have had to upgrade to a 15k a/c, which would require a 50 amp campsite.

camping in hot California, the 13.5k a/c is plenty. but we also use Popup Gizmos and Reflectix on really hot days.

Thanks bikendan. I expected that it would be the 13.5k unit, and most likely will pursue the same.

Anyone have opinions on the 11000 btu units? Or don't bother?
Thanks all.

only the smallest of trailers or truck campers use that small of an a/c. you'll need the 13.5 to keep your hybrid cool, with both canvas ends out.

Living in Georgia a 13,500 just doesn't cut it so I upgraded to a 15k and it works great with the chill grill. I'm curious though about needing 50 amp service for a 15k. I asked about that before ordering it and was told that 50 amp would be required with multiple a units but would operate fine on 30 amps. We have had no problems at all (except getting too cold). Am I missing something I should know about?
