IT IS DONE!!!
The new landing gear leg from Scamp arrived very quickly and shipping was not bad either. The good news is that the tube came with a new leg assembly too. Installing it would have gone smoother if the original upper bracket had not been welded badly when the camper was originally built. It is amazing what a person can make fit with a hammer, crowbar and a mental punch.
To replace the leg it was a matter of putting the camper up on some floor jacks. Removing the a bolt from each bracket. Removing a threaded screw from the cross bar, slipping the old leg out and putting the new one in place.
It took longer to figure out the badly welded bracket than anything else.
Suffice to say, it is done and I am back on the road camping with a plan in place so it should not happen again.
Thanks for everyones help and encouragement.
See you on the road.
