I'd like to relocate the spare wheel on my 4x4 RV (an Unimog) and have to make a new bracket for it. As the spare wheel is in the order of 120 kg and we'll be driving it across rough terain shock loads will be a lot higher than on a normal car with a normal spare wheel...
What would be a reasonable safety factor to use in this case?
