Answer to the PM for everyone else here too
Say that the OP is looking at at Half Ton SUV with a 12,500 GCWR
It is a 7,100 lb GVWR SUV with a 4,250 RGAWR. Gross Vehicle Weight Rating
and Rear Gross Axle Weight Rating
It has a 7,500 lb MTWR, Max Tow Weight Rating
But, that fine print on the brochure says 'curb', or 'base' or some
such TV. One 150lb driver and 'necessary' option (tow option) & WD
hitch
Take the 12,500 GCWR minus the 7,500 MTWR = 5,000 and that is the
vehicle/driver/option/WD Hitch/etc they used to derive that 7.5K MTWR
Now take someone planning to full time for half a year or more
They will need everything they need/want loaded into/onto both the
TV and TT
That 7,100 GVWR TV might then weigh in at close to 7,000 lbs...but
that means the MTWR is bogus, as the MTWR is based on the 'curb', or
'base', or 'stripper' that weighs in around 5,000 lbs and the TV
actually weighs in at 7,100 lbs
So there is a 2,100 lb difference and that difference needs to be
subtracted from the 7,500 MTWR = 5,400 lb as it's 'true' MTWR
What I mean when say the MTWR is taken out of context. Or that folks
take it as an absolute (meaning in all cases no matter what the
TV actually weighs)
In the example above...if the TV actually weighs in at 7,000 lbs
BEFORE Hooking up, then it says that TV only has 100 lbs left for
the tongue & WD Hitch system
Of course this assumes believing in the ratings system.
Also, this thread is for used trucks. The ratings numbers are for
new or those still in the warranty period
Depending on how the previous owner(s) treated the vehicle, it might
still be good for it, or not...
LOVE the math. What you say makes a lot of sense and is a very important point. With the Clipper there should be no problems. However, with 2 occupants in the vehicle and some other stuff that would ride in the vehicle with us, we would probably add another 500 lbs to the base weight of the car + gas. So lets say 6,000 lbs for total vehicle weight loaded, that only leaves us a little over 6,000 lbs for the trailer. Since the 192RBS has a GVWR of 5,900 lbs (although I'm sure we would be quite a bit under GVWR with only 1 week's worth of supplies) we would be potentially cutting it close....and "close" is not what I want to be reminded of 5,000 miles into our trip.
Thanks for your very helpful posting!
All of you have been very helpful, didn't realize how strong the RV.net community is.
