The original tires were 205x75x15 load range C. If that's the size that it still has, look on the sidewall. Max load for max pressure. This number times 2 will give a very close axle rating. Double it for 2 axles, and add a low 10% extra for the tongue weight and you will be close to the Gross Vehicle Weight rating (GVWR).
There should be a tag or sticker on each axle with the max axle rating. Use the lower of the tire or axle ratings to do your calculations for GVWR. The lower number is always the weakest link and going to be the rating for GVWR.
Gross Axle Weight Rating (GAWR) is only the weight on the tires.
