Umm.. That WOULD be illegal.
The weight sticker includes the VIN number and the VIN number IS what the "Tag service" is looking for.
They need that in order to verify the VIN on the title paperwork you have MATCHES the VIN on the trailer.
A 2015 trailer should also have a copy of the paperwork stuck to the inside of one of kitchen cabinets, did you look there? I recall quite a few yrs ago that the manufacturers were required to add that paperwork due to the fact the nearly every sticker stuck to the outside fades or disappears over time..
Barring that, the VIN should also be physically stamped into the tongue frame or a plate with the VIN should be attached with pop rivets to the tongue. If so, take your trailer to your local Notary that handles PA tag/transfer services and they can verify the VIN matches.
Amazingly so, myself, I have never ran into a Notary that has ever wanted a photo of that sticker or even went out to the trailer or vehicle to verify the VIN matches the paperwork..
Perhaps find a different Notary?
On edit..
I guess that some states may not have the unladen weight and GVWR on their titles like PA, that also can cause an issue since they will need that in order to fill in the paperwork correctly.. See if they would accept a weight ticket from a CAT scale for Unladen weight.. GVWR? That would be a guess at best..
According to Keystone website for your model, GVWR is 7800 lbs.. Dry weight will vary greatly due to manufacturing differences and options.
