Thanks for the replies. I agree that taking the wheels off and lowering it on the corner jacks will probably work and I will probably go with that solution initially. I was looking for an easier way.
Short of buying a TM without an air conditioner (not practical in the South) or buying an older model without the side air conditioner, I was looking into the difficulty of replacing the factory unit, which adds 14-1/2", with a new low profile or ultra-low-profile unit.
Two examples are the Dometic Penguin II, which claims only 9-1/2" above roof line or the Coleman Mach 8 (
