Who has a Kodiak 300BHSL? What's your tow vehicle?

The WDH moves some weight back to the TT and some to the TV front axle(which is still added wt to the payload). Then add back on the wt of the WDH itself. Most people will carry some water at some point whether it is fresh or waste and end up with 1000# or more cargo wt. You asked for input and now you have it. Operating your TV at these limits is totally your decision but I wouldn't do it.
