Have a weber baby q, bought a hose that plugs into the propane connector under the trailer and screws to where the 1 pound propane bottle goes. With it hooked up this way I noticed that the Q is a little harder to light, and it takes longer to heat up and the temp guage only goes to 260 degrees. Now disconnected the Q from the hose and let it cool down and put the 1 pound bottle on and lit it and it light much quicker and much faster heating up , and the temp goes to almost 500 degrees. Remember the Q is working thru 2 propane regulaters and slows down the propane. I am going to see if there is a way to modify the regulator and be able to use the 1 pound bottle and thru the reg and when I hook up to the trailer bypass the reg. Have to see what can be done.
