Weber Q series are probably the most popular grills in CGs by far. But, many pass-through compartment doors aren't tall enough to fit a Weber Q through it. I have to pull the pins off the hinges on ours and remove the lid to get it in, despite having a taller than average door. Not a big deal, just something to be aware of. Some put them just inside the entry door for travelling. We got a sweet deal on CL - BNIB Q1200 for only $60 from a lady who got it at a silent auction and had no use for it.
Our Weber is the best grill for BBQ-ing we've ever had - excellent quality and simple design. Does the best ribs ever and when I do them at home, I go out to the TT despite having a big fancy dancy BBQ on the patio. The removable aluminum grease tray is a nice feature. The Weber does have a flat 1/2 size grate available but you can't use two together because it cuts off air flow. Can't use pots or frying pan on it. I removed the regulator and got a new 20' hose with quick connect for connection to the low pressure pipe under the trailer.
The Coleman Road Trip is nice because it has interchangeable grates and you can do pancakes, steaks or use pots & frying pan. But is poor quality and has some dumb design flaws one of which is the big tray under the grates that is supposed to be filled with water to catch grease - I so hated that (and where are you s'posed to dump it in a CG?). We used to have one and replaced it with a Weber 1200.
We do 100% of our cooking outside and because the Weber gets used for grilling only, we bought one of these single burner stoves. Great for a frying pan, wok or pots and heats fast. I removed the regulator & hose and installed a new 20' rubber hose with quick connect. I use it all the time. We put it and the Weber on a roll-up aluminum camping table like in the 2nd pic.
