My Inlaws towed a 14’ van with leaves in it made in 1973 around Australia 4 times living in it with 2 kids full time for 6 years - they never broke anything either and the roads were far worse back then - I’ve seen photos and super 8 footage of the tracks they used to go down - I wouldn’t attempt them with my van. A shovel, block and length of rope was all they had for recovery - Youth, innocence and maybe a dose of stupidity got them through but the van is still going although at a new home now - they only sold it on a few years ago.
I think this sort of overkilled suspension shown here - I’m sure it works very well - needs to cater for modern vans which inexplicably weigh so much now they need suspension to hold them up.
In-laws van weighed 1,300kg fully loaded - you can’t even get a camper trailer that weighs that now.
My 69 Viscount 19’ weighs 1,600kg (that’s with toilet, shower, 200Ah of batteries, 450 watts is solar, diesel heater, 100 litre water tank, inverter, microwave, pump, tv, etc) and has also been towed 1000’s of Km over the last 5 decades - not that I’d want to tow that down hundreds of KM of dirt roads, but plenty did back in the day.
Will be interesting to see if these modern vans are still going in 50 years... [emoji56]
Still have no idea why modern vans weigh so much...
