Welcome, Sunny!
Sounds like you have a treasure. We'd love to see pictures!
Directions are here (post #7).
The
Document Center is a great resource. I checked, and it doesn't look like there is a general owner's manual for a
Fiber Stream, though. We have several
Fiber Stream owners on this site, so perhaps they will be able to help.
Even if not, RV systems are pretty generic and work similarly across a spectrum of makes and years. Appliances change, of course, but you said you have those manuals. Google is your friend. You can google things like "how to winterize an RV" or "how to reseal RV windows" and pull up helpful information and even videos.
And if you're still stumped, ask away!
First order of business is to get this set up to tow safely. According to the thread
Trailer Weights in the Real World your trailer will likely weigh 2800-3200 pounds loaded for camping. You will want a tow vehicle rated for at least 3500 pounds to pull it with, and you'll need to make sure it has any towing related upgrades required by the manufacturer. Read the towing section of your owner's manual carefully. You'll want a
Class III hitch with a 2" receiver.
I also noticed in the
weight data that Fiber Streams have a tendency to be
light on the tongue. Most sources recommend 10-12% of the total trailer
weight on the tongue, so if your trailer weighs 3000 pounds, there should be at least 300 pounds on the hitch. Less than that can make the trailer unstable, more likely to sway in crosswinds or when semis pass. Not good! You'll want to be careful how you load the trailer.
The trailer should be equipped with electric trailer
brakes. You'll want to make sure your tow vehicle is set up with 7-blade wiring and a brake controller. Make sure the trailer's
brakes are adjusted properly and working.
You'll also want to make sure the trailer's
tires are less than 5-6 years old and have good tread (age is more likely a problem than tread; the date of manufacture is stamped in the sidewall as WWYY, week and year). And the wheel bearings may need to be serviced- generally 2 years or 5K miles.
You can see there's a lot to think about and expenses to anticipate just to get this rig on the road safely. You might see if there are some experienced RVers in your area who can guide you and perhaps recommend a good shop to install hitch, wiring, etc.
U-Haul shops are one option, but they are independent franchises, so quality varies.
While you're working on the tow set-up, some driveway camping can help you learn how the trailer systems work.
Remember, though… safety first, function second, cosmetics last.
Happy camping!
