I wonder how well the calculator would work with a StoneRidge 36RK or 36UL? Both models have huge rear storage compartments far behind the axles. I’ve often wondered how the pin weight of those two RVs would be affected if only the rear storage area was used and the front storage left empty. I was very tempted to buy one of these tri-level models when we were looking for a new fifth wheel a couple of years ago.

Might be beneficial for those looking to buy a 5er and having the opinion that the lawyer stickers could not be violated by any amount. I just don't happen to believe the stickers are absolute. Experienced to many stickers being massaged by lawyers ignoring the actual engineering test data.

That's definitely a shortcoming of the tool - there's no way of knowing that he average person with camper X is going to increase the percentage by X% but the average person of camper Y is going to decrease the percentage by Y%. Too many variables outside of getting it close and hoping for a better swag than simply saying "20-25% of the loaded weight".

Either way, I'd love to see scale stickers for folks with those and how much they swing in pin weight changes they see with changes in their loading patterns.

You don't agree with those stickers? Color me shocked.

Where's that dead horse icon when I need it?

Just sat in too many meetings with lawyers playing CYA on things like this for 40 yrs or more.

OC... here's a lawyers sticker from a 2012 Flagstaff 8528RKWS.

Do you ignore these as well when loading your trailer?

I am not sure I understand what you are saying.

It is well established that for safe handling there is a ratio (expressed as a percent of total trailer weight) that must be carried by the towing vehicle.

8 - 14% of camper weight must lie on the tongue and 15-25% must ride on the pin.

Optimum handling occurs at 12% for travel trailers and 20% for 5th wheels.

Trying to size your camper so that the pin load on the truck falls in the safe zone ( as close to optimum as possible) and still not exceed available truck payload requires some forethought.

It would be great to have a tool that will give you some idea before you pull the trigger on too much camper.

I read some of these posts and feel we are diverging from the reason for the thread.

- What follows is a rant ----

This is NOT, repeat NOT, as discussion about exceeding limits; whether limits are hard and fast; or anything BUT a loose idea if a particular floor plan and maximum weight are "right" for your truck (ONLY IF YOU CARE).

That ELIMINATES all you out there in the DON'T CARE camp. So please avoid posting if you are them...

Help add to the process, or stay away. Lots of other places you can spend your keystrokes. Thank you in advance.

I think what ependydad has created is great for those buying a trailer or tow vehicle.
