CAUTION!!! 1978 Trillium 1300. Inspecting the bolts that hold the body to the chassis I noticed that a nut was missing off one of the 6 bolts. Since the trailer is over 30 years old why not inspect all the bolts? JB-80 penetrating oil was used overnight to try to get the rust on the bolts and nuts to cut loose. It was surprising to find that when loosening some of the bolts they simply broke off just under the head. Stainless steel bolts were very expensive and I could not find galvanized ones so I bought regular ones and primed and painted with light coats of Rustoleum. Re-installation was simple but ViceGrips had to be used on top while working under the rig as no helper was available. Lesson: Check the bolts! It would ruin your whole day to be towing, to notice a lighter load, and to look in the mirrors to see only a chassis hooked to the tug. Here are a couple shots of the offending bolts. Larry H

Also, while you're on the subject, not a bad idea to check for the famous frame crack:

Hi Daniel, Thanks for the tip. Looked at frame and it has one
reinforcement each side on the outside in way of the front
mounting bolts. It is 3/16" thick so it should be OK.
Area around the front bolts inspected with no cracks found.
Thanks, Larry

Hi Randy - Another Ontarioan here with a '73 Boler. I recently did a frame-off check, and had my frame completely sand-blasted and painted, along with a new axle/brake installation. I had a welder install four additional 'hold-down' brackets made from 1/4 in. angle iron, and then used 3/8 in stainless bolts, washers, and nuts. to firmly secure my egg. I've always believed "for an extra buck - why not go first class".
