I find it hard to believe the OP has a need for 50amp power with a Cherokee 27bh. Most likely a 30amp unit as its standard features come with a 13.5 ac and little other big power devices. That being said, I use 30amp cords on my unit, sometimes more than one. I hate lugging the 50amp cord around and have little need for it since I rarely use both a/c's at the same time. So it just stays home for use during the week. I have an indoor volt gauge and monitor religiously. We group camp and like to be facing units for a general use area so sometimes longer cords are a necessity.
