My MacBook is 18.5vdc. I could get a DC-DC converter for it, just haven't gotten to it yet - I just did a web search and I see them for about $40.
But on my last RV I upgraded my entertainment system - the original system was 120vac and the RV had no inverter at all - DVD's and TV only with shore power. The Blu-Ray player I installed was 12vdc so I could feed it straight through. The HDTV was 19vdc so I got a DC-DC for it. Worked very nicely - the converter was very tiny and got warm but not hot.
Crank, I think that watching a DVD movie cost me about 5 aH, so the entertainment wasn't a big show-stopper.
But it seems your real problem is space. I was just looking at Lifeline and FullRiver AGM's, and most of the 12V sizes are more than 11" long - you're really limited by that length.
