Should I adjust my towing setup?

All of these forces are foreseeable for the designers of each component and each component designer must anticipate the use of the other's product.  Thus, they have to take the twisting and bending loads into account and adequately design for them and/or advise the users of the load limits and dangers.  In most states, product liability rules require designers to factor in not only foreseeable uses but also misuses that pose a risk of injury.  In other words, if a receiver, such as the one in the pictured Toyota Highlander that appears to have been damaged by torsional loading of a WDH, is not capable of sustaining such loads, Toyota has the duty to warn of the load limits or advise against the use of a WDH.

For example, I bought our Pod from a dealer who sold us both the trailer and a WDH and installed the hitch to our Dakota receiver.  That dealer, is responsible for making sure that the receiver, the trailer, and the WDH all are within design limits and if I got killed as a result of the incompatibility of the three components, he's got to pay the fair market value of my continued existence on this planet to my survivors.  Though it wouldn't do me much good, my survivors would relish in receiving the $7.99 of value my life had, less, of course, attorneys fees and costs of litigation.  

First, its really very easy to get a tongue weight of 600 plus lbs on a 179. Dual batteries, dual propane tanks, and a full fresh water tank does it. Lots of folks on this forum have those mods. 

I am a newbie just got our 179 in August of 2018 and we live in Michigan and have set up the trailer the way we want too.  We are planning on getting out of this snow to warmer climates (Florida and New Mexico).  With all that said I finally got around to having the rig weighted yesterday and have a question even after reading most the posts on the forum concerning tongue weight.  I am pulling the r-pod with a 03 Jeep Grand Cherokee no problem there with the gross weight of the rig.  I am not using a wdh and have a tongue weight of 450 lbs, finding that weight by weighing the tv without anything hooked up to it then attaching the tt to the tv and weighing just the tv axels (2) and the difference is the tongue weight.  Got that.  Then I pulled the tv and tt on the scale (all 3 axels) and found out when I subtracted the tv's weight from the total rig I found out that I was just over the axel rating of 3500 lbs.  Also impacting the weight is when I weighted the rig I had snow load on top of the r-pod, guessing that load to be about 200 lbs and taking that load away from the gross weight of the rig gives me a little breathing room.  And yes we treat our r-pod very poorly in Michigan, allowing the snow to accumulate on the roof.

Here's my question to calculate the tt axel load do you subtract the tongue weight and tv weight from the gross rig weight to determine the load on the axel of the tt??  That would seem to be logical to me, but what do I know.  That's the reason for the question.  Any help would be appreciated and I have load range D tires so that should not be a problem.

Thanks in advance

Thanks all the light bulb came on when I thought that I had to subtract the tongue weight with the tv's weight to get the trailer's axel weight.  Just wanted to make sure I wasn't missing something.  I do have enough breathing room on the trailer's axel weight to enjoy our trip coming up next week.  Thanks again furpod and offgrid.
