Hi Cheetah - Our Coromal was a 2004 - so perhaps we had a good one.
You are right - riveted Aluminum frames do not stand up to corrugations,where-as a wood frame will flex - but then wood and glue/staples are also prone to damage. As I understand it, the jury is still out on the choice. The dearer brands are mainlyl welded aluminum frames.
Also - the word "off-road" gets watered down until it means smooth gravel surface.
I found the article "why wheels come off" by Collyn Rivers (see my SITE LINK above) very thought provoking. His point is that without shock absorbers, the impact from a bump/pothhole/corrugation hammers the spring/
suspension up - the van weight pushes it back down where the road impact hammers it back up etc.
The tyres will remove some of the impact energy, and
the springs will heat up also removing some, but the end result is likely damage to the van (esp if you have the tyres at the recommended 50psi). Lower tyre pressures help, but the whole design of shock absorbers is to dissipate that energy via heat. Price/cost cutting is the ONLY reason why "off-road" vans do not have shock absorbers . The better makes do have them.
Our Surpeme does NOT have them - but then Supreme warranty is very limited - they EXCLUDE things like wheels,
suspension, stoves, fridges, awnings,, pumps,
water tanks, gas bottles, battery chargers, radios, hot
water system, doors, windows, etc....and if caused by any negligence on your part. So perhaps they know they can avoid almost every claim for damages -for example if your driving or tyre pressure etc contributed to the damage. (as you may suspect - I think the reputation they had, no longer applies - even in the slightest)
Our modern rushed society also puts a mind-set of going too fast. Learning to slow down is now needed more than ever....Keith
