Hey Jeff thanks for the information! I wasn't able to pull any information off of that serial number you gave me. If your current Dometic AC has a rectangular shaped 6-pin connector you can replace it with the Dometic Penguin II High Capacity RV Air Conditioner item # DMC29ZR. This is a 15,000 BTU AC unit that is only 11-1/2" tall.
If you have a 2018 Forest River Wildwood Heritage Glen 5th Wheel Trailer like you listed in the fitguide the Penguin II item # DMC29ZR is listed as a replacement option.
If you have any additional questions go ahead and throw them into the comment box below and I'll be happy to answer them.
