Story:
Just purchased a new 260 RD from Greenway RV in Wisconsin Rapids, WI. I saw that a spare bedroom air cond was optional, so I ordered it. A 13,500 LOW PROFILE . 260 rd is 12 ft high, so additional air raised it to 12' 8" as confirmed by dealer AND factory. I have 13' door on my storage.
Well, the best laid plans......factory was out of low profile AC, so they installed a 15,000btu standard AC (14" high).
I tried to park it, NO banana.
Called the dealer, he tried to get GD to solve the problem - unable, NO low profile 13, 500 available.
Dealer, said he would help, wanted happy customers, Had one (1), 13,500 low profile in stock and would switch out for free (nada, nothing, no dinero), just make a date and give them 1 hour. I did, they did, and all worked out.

Kudo's to Greenway RV in Wi Rapids, WI. A excellent dealer......with an excellent reputation and repair facility.
