Purcell Trench grills are worth every penny, a fabulous piece of equipment.  For longer trips I carry both the Streamside Voyageur and the Voyageur.  They are impossibly lightweight and made to last.  I throw my fish right on the Streamside (that's the one with the mesh) and it does the job beautifully.  Then I just leave the grill in the fire and burn off most of the fat and leavings after which, a quick wipe and it slips back into its sleeve so there's no black crap all over everything.  Cooking directly on the grill is best for meaty fish like trout but because of the tight mesh I find I can easily grill bass or Walleye as well.

There is some warpage when the grill is set on a hot fire but after a couple of uses it settles down.  I have never had a weld break.  Don Tryon, the owner, will replace any grill that should break but he says that in all the years he's been manufacturing these that kind of damage is so rare that it's not worth talking about.  This is an extremely well engineered and designed item, very well thought out.  Don, by the way, is an excellent person and an avid outdoorsman.  I really enjoyed doing business with him.
