I'm a new member here and hopefully someone can help. I bought a 2012 FR Grey Wolf 28BH. My question is can someone out there give me the measurement from the ball to the start and finish of the LP tanks. My purchase settled an estate and it's 10 hours from home. There is no one who can get the measurement for me at the other end. I would like to order a WDH now so I have it to get it home. But I don't want to order one that doesn't clear the LP tank mounts etc. Thanks to anyone who helps in advance.
