Gas hob with grill

As we've only used our oven once, and that was only to see if it worked!I was wondering if there was such a thing as a 2 burner gas hob and grill which could be fitted in place of our cooker and gain a bit of storage space by deleting the oven? Our van is a 1999 Duetto, I've had a pretty good look around but so far not found anything, basically we want to keep the hob and grill that we have and delete the oven.
Thanks

Check chandler's for suitable hob/grill as used on boats

I'm sure I've seen similar in VW conversions, which have less space.

I don't use my oven or grill. I use the oven like an extra cupboard  

Just another thought - the Harmony and Rambler came without oven, so maybe AS spares could tl you what make/model of hob/grill they used as size would probably be same as complete oven.
