Rotisserie Pork Tenderloin

"I like gadgets.  Especially gadgets that help make delicious pork tenderloin over an outdoor fire.  Rotisserie pork tenderloin isn't tons better than just slapping the tenderloin straight on the grill, but it is a touch better.  And after a bit a prep work to tie the pork tenderloins (there are two parts here) to the rotisserie without it sliding around as it rotates, it is worth the time it frees up to have a few beers while you are waiting for it to finish cooking.  Cook this to an internal temperature of 140 degrees and you'll have a moist, tender and delicious pork tenderloin...."
