Hi Jean ... only Scamp
recommends taking the weight
off the torsion bar suspension ... and I've only heard of a few folks actually doing it.
says the problem only occurs when the trailer sits idle for long periods of time ... so is there any way you could once a month ... or so ... just hook up the Scamp and take it for a ride? Exercise the suspension.
Part of the composition of rubber releases chemicals when rubber is used like rubber is supposed to be used ... i.e. squeezed and bounced.
I know this is good for tires
... although today's tires
are less prone to developing flat spots than older tires. But tires that just sit are more prone to the effects of weathering ... and don't last as long as tires that are used. Not using tires actually shortens their lifespans.
If you do jack up tire to take the weight
off the suspension, I'd block it up as close to the axle
as position, say on each side of the axle, to avoid any problem with bending the frame (which can happen with any trailer, not just our beloved little fiberglass wonders).
We love to winter camp, so our trailer never sits still for more than 3 or 4 weeks. Even then, I'm apt to go hook it up and pretend I'm leaving town. Tow it out to the local park, play ball with my dog.
I sincerely believe exercise
is just as good for the suspension (not to mention good for my wife, dog and I) as blocking.
