Michele,
Welcome to SOC.
Please feel free to ask away on questions.
Is your trailer the RD or the FD? You may want to go to the "Files" tab at the top of the page and then click on then "brochures" tab, then go to page "3" and then click on the "1982 travel trailer button" (it is the top of the 3 '82 brochures). Click "download" and you will have some info as to the weight of the trailer and tongue/hitch weight loads, as shipped from the Sunline factory.....back in the day.
What tow vehicle do you have? Pictures showing the hitch hook-up is helpful. Many people have the hitch to high or to low, etc.
Is you trailer winterized at this moment or are you living in it? If you are living in it, is there a electrical hook-up being used? How are you handling the waste generated?
As you can see, we can and will be asking as many or more questions than you, this is normal.
Please post, we are here to do the best we can to help and share our experiences...."Good, Bad and the Ugly".....as well as the beautiful. I just had to do a play on words....sorry.
