Bob - there is so much misinformation out there that it will make your head spin. Just look at the RV.NET forums for a good indication.
We have no idea of your truck since your signature does not have any clues as to its capacity, but it does look like an older Tundra, going by the picture in your profile. Added to that we would need weights of the payload in the truck and the loaded weight of the trailer. You could well be overloaded.
Meanwhile you can check the
Trailer Life Towing Guides to show what the truck's capacity could be fully loaded with gas and I believe with a 150# driver. Anything other than that reduces the payload, and working backwards from the remaining payload, you can calculate the max gross weight of the trailer.
