I was looking at the attached site of a Trillium trailer brochure and saw a photo of a new trailer. The clearance on the tire and start angle on the arm looks like a 0 degree. I am wondering if the rubber deforms over the years so the start angle appears as 15 degrees up. This would also result in the travel of the arm also being reduced.
I would expect these photos are all parts used by Trillium
and I agree with Brian that the start angle on the unloaded axle
looks like-15 degrees. I loaded the page into photo shop and lightened the loaded shot and agree with you that it looks like 0 degrees. That would indicate about 15 degrees of movement under load(mine moves about 6 degrees). Because mine is about 21 degrees up in loaded position I have less space between the wheel and fibreglass above but still enough at about 3". My only concern is the condition of the rubber rods. Because there is no free play in the unloaded position I am going to assume the rubber is ok other than being slightly harder than new condition.
On a different topic I found some ensolite trim yesterday( there were some pieces missing on mine). I also heard about someone on the east coast who rebuilds the cooling units on the old Dometic fridges(don't know the cost yet). Since the fridge
in my trailer was sitting in the middle of the floor totally disconnected this may be good information. I still havn't done much on the trailer because I don't have heat in the garage yet. I'm going to go with radiant tube propane
because they claim it's 30% more efficient than forced air.
