Our 5th wheel came with the "semi-generator prep package" that included a Marinco 50A twist-lock receptacle on the front of the 5th wheel (please excuse the water spots on the camera lens.) Despite the 125V designation on the cover, it's a 4-conductor (L1, L2, N, G) receptacle as used in 120/240V split phase center tap neutral 50A RV service.

The location of the receptacle is just to the left of the front compartment bay door as seen below.

Using a 50A twist-lock to 30A male adaptor, we plug the 5th wheel into 2 paralleled Yamaha EF2000iS generators we carry in the bed of the truck using a standard 30A extension cord that runs along the pin box. The generator prep package includes a transfer switch, generator control panel, etc. that makes the use of this setup to pre-cool the 5th wheel fairly painless.
