We have the roadtrip LXE as well, and have used it for 3 years.
It works well for us.
Common Complaints I've heard and my opposite experiences:
*Hot spots and burns food - I usually have the flame turned down and haven't experienced the burning. Yes, parts of the grill are hotter but if you pay attention while cooking it has not been a problem for me.
*Gets dirty and hard to clean - I never understood this one. Yes, grease gets on the steel below the grates, but just wipe it up with paper towels and a scrubby when you are done. I thought it was easy to clean...but you DO need to clean it, and not just leave it forever.
*Can't be hooked up to low-pressure quick connect - Not true. There are several videos that show you how to do this and now even a commercial product that you can buy to do the conversion. (It is easy, and I've done it).
*Can't cook with the lid down - again, I've done this but you cannot have the burners turned up all the way when you put the lid down.
*I like the fact that I can grill meat, or make pancakes on the griddle or make soup or coffee on the stove burner. One grill that is versatile for many uses.
*As others have said, it folds down easily and I have the bag with wheels that I store it in.
I'm sure there are other grills that may be better at doing one thing (like grilling!), but this grill/griddle/outdoor stove works for me because one device does several things pretty well.
