I can see the briliance in the curved hatch. it gives you soo much headroom, from lifting the bottom up 6 feet that you can walk under it and not have to worry about hitting your head, as you go into the galley. I have a flat hatch and have to crouch under.
I have never owned a coleman or gas lantern. I can see the advantages to one for sure. I may or may not invest in one. well see but the idea does intrigue me and i guess with anything there is a group that enjoys something in life. I am sure there is a forum for earhtworms yet not looking for it. and since those are popular with campers this is a good place. i may or may not get into dutch oven i just dont know. trying to keep it simple.
