2013 DRV-new 5th wheeler

[BeachMan]

Hi All,
I have been shopping for a high quality (new) 5th wheel under 40 ft and today bought a 2013 DRV Mobile Suites. Hopefully I didn't make a mistake but seemed like an awesome quality fifth wheel. I found out today that the previous owner installed the 3rd axle aftermarket, (I thought the 3rd axle was factory). After speaking with a rep from DRV I am convinced that this is a good thing by keeping pin weight about the same but adding additional payload capability.

Will be towing with a 2017 F-350 4x4 DRW 6.6l diesel, 4.10 axle

Any thoughts on the 3rd axle add would be appreciated.

Thanks,
Beach
