355 mbqs pinbox height

[DurtymaxLineman]

Hello all, new to 5ers and the forum. Been researching a lot, but this is my first post. I am looking to buy a 2015 jayco 355mbqs and am trying to figure out what the height of the mounting holes for the pinbox wings are are? I cant seem to find anything and jayco service said they are 50.5"

That doesn't sound right. I plan on running a reese goose box because I have a lifted TV with a flatbed and goose neck ball already installed. Sorry for the long winded post, but dont want to drop coin on a 5er that I cant tow.

Thanks in advance.

I don't know off hand what the height is but my 2019 355mbqs is a little nose high on my stock f350 srw. I have the B&W slider all the way down and I'm thinking about raising my pin box up one hole to the upper most setting to get it as level as possible.
