Manufacturers like Forest River do not list the dimensions or part numbers for pretty much anything that they use when building their trailers so you will need to measure the cutout hole in your counter to determine the correct fitting replacement sink.
For example, the Better Bath RV Kitchen Sink # LC385313 is 27" L x 16" W with the inner portion being 25" L x 13-7/8" W so if it was undermounted it would fit a cutout hole anywhere from 25" to 26-1/2" in length and 13-7/8" to 15-1/2" in width. view full answer...
Yes, you can use the Gooseneck to 5th Wheel Trailer Coupler Adapter part # KPG5-R25-IP to convert the Ram Gooseneck Coupler part # GCPN-25008 from a gooseneck to a fifth wheel attachment. In order to do this you'd simply remove the gooseneck inner tube from the old coupler and replace it with the fifth wheel inner tube. view full answer...
