Don't know if this does what you are looking for. It certainly handles a 32". Ends in a couple of minutes but will doubtless be on again/elsewhere on ebay.
Far be it from me to say you cannot do it, should not do it etc. Your tv - your van.
I bought a Samsung 22" for my caravan but the sound was awful due to the tiny speakers. Changed it for a Philips 26" which is ideal, although a tad big. I think you will be pushing it with a 32".
