I ordered a custom made cargo trailer a few years ago. It was delivered with an incorrect weight sticker. The sticker used the wrong axle rating to calculate GVWR. I called the factory and they sent me a new corrected sticker.
A number of years ago I called the factory that built my travel trailer. The sun had faded my weight sticker to the point it could not be read. I asked for a new sticker. One was mailed to me. All was correct except the date of manufacture. It used the current date as the build date. I called the factory. I was told by the clerk who made the sticker that the date could not be changed as the machine spit out only the date the sticker was made.
I have been to a number of RV factories and never seen a scale. I went to Google Earth and looked at the Grand Design factory in Middlebury. I did not see a scale.
The take away from all of this is do not think that the stickers on an RV are always correct.
