Hi LB,
We hired a couple of Kampers before buying ours. One was a 2010 model with the BBQ and we found it impractical, especially when needing to have two burners going at the same time. You can also do the same thing on a frypan as the BBQ anyway. We would end up taking the hot plate off and putting pots, pans and kettle on the trivet. We bought ourselves a Weber Baby Q so now we can BBQ properly, roast and bake while still being able to use the 3 burners available in the KK.
I guess you can't go wrong with the KK solar panels, their customer service is very good.
