alco suspension problems?

Do a search but I don't think I've seen many posted.

I am in the marine industry & have never heard of any failing on boat trailers.

However, that is not the case with camper trailers.
I think if you do a search, you will many instances of problems or failures & long delays in getting replacements or parts in more remote areas. On the other hand, I know of some that have coped with the rigours of the Outback with no problems whatsoever.

If you don't want to run to the expense of independent suspension, maybe you should look at rebound leaf suspension with shock absorbers. Do your research carefully, as you will find that many 'off the shelf' camper trailers are way oversprung, which doesn't give the suspension the opportunity to 'work'.

I've had two fail, one on a camper and one on a caravan, the van one was a Jayco van that the GTM exceeded the rated load of the axle.
When it failed in nth western QLD it was an expensive tilt tray trip to Mt Isa where it was replaced with leaf springs, with which it towed much better BTW. After much haggling Jayco did refund some of the cost associated with the breakage and repair.
The camper trailer one just plain wore out, grit gets in the space between the rubber and the steel tubes and grinds the rubber away and it will eventually happen on trailers used on dirt roads.
Personally I'd never have another trailer with it as it is impossible to fix or even bodgy a repair on the side of the road, give me eye to eye leaf springs any day, rarely break and when they do can be repied with basic tools an bush mechanicking (sp)

My Campomatic CT has AL-KO hubs and internal electric brake hardware - don't know who makes the springs but the shocks are Tough Dogs - I've serviced the hubs a few times myself now - amazed at how much of a beating they can withstand (thats the value of good industrial design for you) - they have covered a lot corrugated kms and seem fine in all respects.
