2. Monaco did that because they were cutting cost NOT because there was an operational or ducting issue.
3. NEWMAR has installed 15k (2 and 3units) for 15 years on their ducted system with np problems
4. Tiffin installs 3 15k ducted AC units on their 40 to 43 foot motorhomes
5. The 13.5 and 15 k IF you have a wall tstat will have a freeze sensor that prevents ANY possible freeze-up.

7. It seems the dealer is trying to NOT have to spend another $1000 to fix their mistake.
8. IF the extra AC has roof mount controls, you do have the possibility of freeze up, but you can stop that by always running the fan on HI/cool.
9. It is ALWAYS best to have the largest BTU AC units on a RV, as it is better to have MORE potential cooling capacity that nominal capacity. Doug
