Well, mine is technically a 3000, which means it had a side burner. I took it off because I have never used it, and replaced it with a side table. The four and five thousands start getting away from the classic look of the 1000, I just like the extra side shelf. I guess my personal preference lands squarely on the 2000. Open lower cart area, natural gas, two side tables and for me no flip up side tables. I recently hardwired an electrical receptacle outside right by the grill so now I can run the rotisserie without an extension cord. I'd rather stick with my own use preferences and keep the features of the grill that I like, use and enjoy the look of. Hence wood slats, for example.
