Just to dispel some myths....37' non slide well insulated motorhome, two 15,000 btu roof top airs, awnings out, shares down, exterior window shades and a misting system on patio awning. The place, Pahrump, Nevada, the outside temp, hovering at about 115, inside RV, 68 degrees!
I've owned our motor home for close to 20 years and I travel in hot months....so it's not a one time occurrence!
The myth dispelled....that air can only cool down 20 degrees below outside temp! The accepted rule of thumb is 20 degrees less than the Ambien air entering your return air duct of your unit( up to its max cooling ability). That's my real world experience and my I understanding as to how it all works....your results will, in fact, vary!! LoL
You are correct BUT, you cannot compare your RV and length to RV's built LONGER (43 versus your 37) AND you have no slides Which is a GOOD thing because slide rooms are big air leakers even if they do not leak water inside. Doug
