Our experience is 4 years old, but here it is.
We originally bought (in 2010) a Weber Q-2200. I bought a separate, "squatty"10-lb propane tank as we weren't comfortable having a high pressure propane line snaking across the grass from a T-connector on the rig to wherever we had the grill. I got a base ring and bolted it to a stow-bin floor to retain the bottle during travel.
I didn't realise that the Q-220 was about 3/8" taller than the stow-bin doors if the lid was on! I got fed up of removing the lid for storage/travel then putting it back on for grilling.
We bought a Q-100 for the RV and designated the 220 to the patio, replacing a behemoth 4-burner unit big enough to land a 737 on.
Now retired RVers, we have two grills for the occasions when a large group is visiting (not infrequently with a family as big as ours).
We've had excellent service from our two Webers, but the regulator on one of them has died. Replacement before next season!
