Wiring

Trillium Wiring - Tow Vehicle

Please follow the "standard" industry wiring code

Black (positive, battery) - min. 10 gauge

White (Negative, ground), min. 10 gauge

Green: Tail lights, min. 16 gauge

Red: Left turn, min. 16 gauge

Brown: Right turn, min. 16 gauge

Blue: El. brakes (optional), min. 14 gauge

Yellow (center terminal, optional), brake lights, min. 16 gauge

The separate brake light circuit can be utilized when the tow vehicle is so equipped, as Trilliums are equipped with this 'extra' wire.

Colors refer to the stamping on the connector terminal block. Circuit wires should be of the same color.

The above color codes also refer to the wire colors within Trillium trailers in the 12 volt DC harness.

A "How To" guide can be downloaded here to provided detailed instructions on tow vehicle wiring.

Service

We have been contacted by many owners of Vintage Trilliums for service & maintenance questions.  For questions other than those listed, or more detailed help, please email to Service@TrilliumRV.com.
Below is help for some common items for VINTAGE Trilliums.

Water leaks - (Other than from window condensation)
If water accumulates in the storage compartments only, it must be coming in around the various hatches (cable, water, etc.), or lights on the lower section of the trailer. Seal around the top & sides of the fixture.
If there is water in the storage compartments and the cushions are wet, then water is entering around the windows or center seam.
The center seam molding is hollow. Therefore, a bad seal on one spot on the seam may show up elsewhere since water can travel inside the molding. Usually, a close look at the existing seal will determine if there are gaps/cracks/void sections in the sealer. Since the resealing job isn't that difficult, resealing all the attached parts/fixtures/molding is recommended.

Sealing
All Trilliums were sealed at the factory with an acrylic sealer. Silicon will not stick to fiberglass for extended periods of time.
To repair/reseal the various sections, first wash thoroughly with soap & water. Once dry, wipe the surfaces that the sealer will come into contact with, with acetone and a white cloth. (Acetone will remove color from fabrics, and transfer it to the trailer. Also, be careful not to touch any of the decals with this cloth. Acetone will remove this color as well.) Acetone can be purchased at most auto parts stores. Be sure to dispose of rags properly, as Acetone is very flammable.
Once dry, and completely free of loose dirt & contaminates, reseal using GE Maxx 3500. This is an acrylic sealer found at most Home Depot stores and similar. It should be applied the same way as any other caulking job. Be sure to follow the instructions on the tube, especially about ambient temperature. Cold will add to the cure time, which could be a problem if rain is eminent.

Refrigerators
A poorly working/not working fridge can be recharged by a qualified Dometic repair center. Another option is to replace it with a new generation of 12 volt compressor fridges. New Trilliums have this type of refrigerator. There is relatively low power consumption, and it isn't sensitive to being level. Consider adding a second house battery if the use is mainly "wilderness camping". These fridges are also slightly larger, so a small surface frame may need to be added so it it will fit properly.

Interior vinyl seam cover strips
If these strips have shrunk over time, or do not lay flat, remove them and place in very hot water. They can then be stretched to fit as it was originally. Be sure to do this while the plastic is still hot-very warm. 
Currently, there is no replacement available. However, an effort is being made to find a source for those that are in need of this seam molding. Once located, it will be noted here.

Tires/Wheels

Trilliums were originally supplied with B78 x 13 tires; early 1300's had A78 x 13. Today, this tire is an ST 175/80R x 13, (Load capacity 1360 lbs.). The recommended minimum tire load capacity: Model 1300: 1100 lbs; Model 4500: 1360 lbs. (Each Tire). Set the inflation pressure to the maximum as stated on the tire sidewall, and check regularly. Most tire failures are the result of underinflation and/or overloading.

ST tires are manufactured differently for the trailer industry. They will give better performance, last longer, and don't have to be de-rated. Even though trailers in the 70's & 80's were originally supplied with P (passenger) tires, it is strongly recommended that ST tires be used as a replacement today.

Maximum wheel/tire diameter is 24 inches, to still fit inside the wheel well. Many ask if 14" wheels would be an advantage. No, since you are limited by the max. diameter.

Vintage Trilliums Weight

'Standard' 1300 about 1,000 lbs.;   4500 - about 1,300 lbs.

Weight to be added to above :

Factory installed options

Equipment installed by other owners 

Water, Propane, and Food

Bedding, Kitchen Gear

Personal Gear

Campground Gear: Leveling blocks, wheel chocks, extension cords, water hoses, etc.

Brakes
All Trillium factory installed axles had brake flanges. 7 or 10 inch electric brakes can installed by most RV service centers. Read your tow vehicle owner's manual to determine if the trailer should have brakes when towed with it.
