1979 Trillium 4500 for sale  $10,500

Come see this vintage Trillium in wonderful Sedona Arizona!  It is toothbrush ready…..meaning all you need to do is throw in your toothbrush, hitch it up and hit the road!

This 1979 Trillium has been kept in an RV garage it’s entire 40 year life….. that means it has not been subjected to prolonged rain, wind, snow, or desert sun.  It is only outside when camping, otherwise it has been garaged.  Its condition shows the love!  I know the entire history for this Trilly, and it has been well maintained, with all the original paperwork, receipts….and a real rarity,  the original key fobs, tank/spare tire covers and owners manual.     It is in near original maintained condition.  It is a real head-turner on the road, at rest stops and in the campground. If you like vintage, without some of the head-aches of vintage, this Trillium is the one!

It has a clear and clean Arizona title

Full history is known and documented

Inspected twice in the last 3 years

Gross weight 2000 lbs, 125 tongue weight

15 feet from ball to bumper

13 feet of living space – sleeps 4

This Trillium can fit in a regular garage with an 8 ft garage door

  • The dinette has two sizes with a table leaf that stores in the pantry and it folds down to make a double bed.  The bed is comfortable, and it is surrounded by windows on 3 sides so there is great airflow.

But Wait, There’s More!  

  • Bike rack for two bikes attaches to back bumper

  • Wheel chocks
  • Porta-potty
  • Gas Grill
  • Trailer dolly  - makes it easy for one person to roll the Trilly

This is a wonderful little trailer and has served my family well.  The only reason we are selling it is we have just outgrown it and are sad to see it go. Made in Canada and very rare, these are considered by many to be one of the best quality fiberglass trailers ever built, in part because the fiberglass wraps completely around the underside of the trailer.  There is no exposed plywood that can rot.   

This is a cash and pick up sale in Sedona Arizona. Please ensure you have a vehicle rated to tow 3000 lbs +.  I would recommend a truck or full size SUV.  Ensure your vehicle has a real tow package with trailer brakes/ lights and a 2 inch ball hitch that will be level with the trailer.  Please have experience in towing a trailer.  My location has 6% down hill grades and steep up hill climbs.   In good faith, I cannot sell you this Trillium if you don’t have an appropriate tow vehicle, towing equipment and some experience in towing.
