starcraft grill

I just purchased a 1995 starcraft starlounge xl tent trailer for elk hunting in colorado. This hunting trip was the best Ive had now that I have a trailer with a furnace and I didnt have to get up every hour to place wood in the stove of the tent. Im looking for a gas grill that I can utilize on the rail system like the 3 burner stove that came with this model camper. Anyone out there have any ideas where to get this item? The local dealer has a new grill for $180 but Im not sure if it will work with the rail system of this model and price is high.
