Just as a bit of FYI. I am not familar with the roadtrip or the op's other appliance.
Any appliance that uses disposable torch/lantern bottles is a high pressure unit meaning the regulator/control valve etc that the tank screws into reduces the pressure from tank pressure to 1,2,or 3 psi whatever the unit was designed to work with. A normal system either a house or RV uses either two regulator or in the case of our RV's a "twin" stage regulator to reduce tank pressure to 11" water column (approx 6.35oz ) So any unit noramlly requiring a disposable bottle will have to be connected between the tank and the existing RV regulator or they will not burn correctly. Any conventional gas grill or appliance that runs off of a 20# cylinder could be connected in after the RV regulator.
Hope this helps
