Thanks for all the input and helpful comments. We now have a series 3 Santa Fe on the drive, we were fortunate enough to find one which happened to have a towbar, so saving a heap on having one fitted.
Hoping this means a normal year of caravanning for a change. We can't wait to get out.
If it has a Witter tow bar, make sure it hasn't dropped, there was a recall to tighten the cross member to the chassis fixing struts., bolts to a higher torque.
This is due to only two bolts on each side allowing the cross member to "drop"
Witters fix was to raise the tow hitch on a jack and increase the torque on the 4 bolts by 10 ft lbs.
Also early Witter fixed tow hitches on the Santa Fe's the Alko hitch was about 1 inch further back from the centre of the wheel axle. Not a big thing, BUT.
I changed mine to a Tow Trust Towbar, a better designed one, maybe Witter changed theirs after 2016.
Factory fitted towbars on a 2014, like mine were Witter with a Hyundai pno.
Don't loose sleep over it though. Just dream of Spiders and Scorpions. 🥴
