outside gas grill connection?

[harrtenn]

I have a 2002 coleman cottonwood with the ability to hook the inside stove to the door on the outside of the camper via a low pressure quick connect gas input at the bottom of the camper by the little half door. I don't want to use the stove that came with the camper, I want to use my Coleman 2 burner stove And my portable gas grill and use them at the same time if need be, they both run on little disposable bottles. Is there a way I can hook those 2 items up to that input so they run off the big tanks on the front of the camper? Sorry for not knowing the correct terms I'm just learning:eyecrazy: What exact hoses do I need, connectors t's etc. to be able to do this? I looked at my manual it doesn't show what to use, it shows 2 different kinds of inputs at the bottom of the camper (one with a lever - which is High pressure) and one without a lever which is Low pressure-- this is the one I have.
Thanks to anyone who can help with my lengthy request:o

you'll need one of the tees to put on you main tank and a hose!
Your low pressure is 0.4 psi and your coleman 2 burner needs 15 psi or higher!
