Hi fle,
Welcome to Sunline Owners Club and congrats on your new truck camper!
This may help, in our files section we have a copy of the 1973, 1975 and the 1977 truck camper brochures. I looked quickly and the 73 and the 75 brochure shows floor plans and the model numbers, but no weights. In the 77 brochure by then the brochures became better and have the model numbers and an approx weight. If your floor plan lines up with one of them in the 77 brochure the weight may be in the ball park. Not knowing what you are doing with the weight number, do not trust it as gospel more of what league your in. On these old ones, you may have to get the truck and camper weighed at a truck stop and then go back a 2nd time with the camper off the truck to back into the real weight.
To get to our files section, you need to be logged in, then along the top of the screen are tabs. Look for the one marked FILES, looks like this
Click the files tab and once in, look for "Brochures" Then scroll to year and download a PDF of the right brochure. Some times the truck campers had their own brochure, other years they where mixed in the yearly brochure with the travel trailers, fifth wheels and the truck campers. The methods changed over the years.
We also do have a Sunline Truck forum area on the our site which may help. See here
Sunline Truck Campers - Sunline Coach Owner's Club
We do not have as many truck camper members as we do travel trailer members but many of the topics do cross over into the TT line and we can help as we can.
Good luck with your camper
Thanks
John
