Spare Tire Rack Failure - Third trip out with new RV.

Good reminder.
Pretty common problem over the years.

My last trailer had LT235/85-16 E. The spare was a bolt (clamp around) on the bumper tube.
To keep someone from borrowing the spare and keep it attached to the tube bumper I use a security chain through the wheel and around the tube...just in case the nuts work loose... or someone with a wrench plays a bad trick.
