I hope that you guys can help us make a decision.
We have put a deposit on a Roo 21RS, which we love and think will be great. However here is the problem (and I am sure that you will have heard similar stories before)
We have a 2009 Pathfinder with a tow capacity of 6000lb, the Roo actual sticker weight is 4029lb (Dry weight is 3659lb) so assuming 309 lb for a full tank of water and 200lb of other gear, 50lb in the water heater, 40lb of propane and 20lb of batteries this takes me to 4648lb or there abouts leaving me 1352lb of spare towing capacity (22% spare capacity - 20% is a rough guide that I have read many times on this forum)
Now my issue is with the tongue weight - the Pathfinder has a max tongue weight of 600lb, and there is no mention if this is with a weight distributing hitch or not. The Roo 21RS has a listed dry tongue weight of 594lb which is very close to the hitch rating. I am deeply confused about the function of the weight distributing hitch. The dealer seems extremely genuine and says not to worry, the WD hitch will spread the load and about 30% will go back to the TT.
Now using the hitch weight ratio of 16% (dry hitch weight / dry axle weight) and including the additional weight that we think we will be adding, this would take the hitch weight to 744lb, subtract the 30% and we would have a hitch weight of 520lb and all is good. OR assume a 12% hitch to axle ration and no impact of the WD hitch and the hitch load goes to 558lb. I have also read that 12% is a good rule of thumb to use.
So the bottom line is - how can I determine if this combination of TV and TT will work ? There is so much information out there most of it conflicting.
Many thanks in advance
