Good conservative guidelines for those who need to ask.
We are all different. I carry most of the provisions and such in the TV. Will admit there are times when I wish it was a tandem axle trailer just for the safty margin (like twin engine boats and planes also but grew up on the Carribean) & would not want more than a 2922KS.
This is an area where I think TM advertising plays a little fast and loose with the facts and have wondered why the official specs for my 2720SL (dry weight 2865 lbs) does not match the sticker under the sink (UVW - Unloaded Vehicle Weight 3243 lbs) and the official tongue weight (392 lbs) is different from actual (460 lbs) Without AC or battery maybe ?
That said I must admit to having towed a lot more with a lot less but then having done quite a bit of road racing in my yout, I tend to "drive gentle" (doesn't make sense ? Would it help to know that when you are going really fast & is quite different from what most think of as "fast" it really feels a lot like you are driving on ice & anything sudden is wrong. It also taught me to always drive a few hundred yards in front of the car because what you are doing now affect how it will act then.
In fact for the fortunate few there is "fast" then there is a really undrivable region, and then for the artists there is a "really fast" plateau where to the bystander it really looks slow just the car is always in exactly the right spot and pointed in the right direction. It is magical.
Kinda like what great artists say to neophytes "if you have to ask, then do this..."
ps I also like to know exactly what is going on. (and that is just one of three pages).
