This is my second 5th wheel. This is my 1st Keystone, a Raptor 441 Toy Hauler (as soon as it's built). My wife and I will be living in it full time for the next couple of years. I will be towing with Ford F350 Super Duty with the 6.7.
Welcome to the forum. Lots of great information and lots of super knowledgeable members ready to help with any questions and with most problems/issues you might have.
That Raptor 441 is a 45' 21000 pound triple axle "MONSTER"... I do hope that F350 is a dually....
