I wish I knew the weights of all the RVs that were ever made, but I don't :-)
Your best bet is to contact the manufacturer of your RV. In your case the Innsbrook Travel Trailer you own was manufactured by Gulf Stream Coach Inc.
You can contact them at (800) 289-8787.
Whenever you need to get any important information on an RV you own, it is always best to contact the manufacturer first. Your lucky because the company that built your RV is still in business, there are a lot of RVers out there that can't say that.
