[Star Wars] Why is the Jawa sandcrawler bigger on top?

It seems to be an unstable design prone to tipovers as it climbs and descends hills. Given its massive height it seems also prone to tipster when travelling parallel to a slope. In short, it seems like a terrible design.

Shade. 

The top is living space, mostly open. The bottom is the engine and storage. 

So it's not top heavy at all, it's roomy and there's more shade at the bottom than would be if the top wasn't as big. 

It's actually quite elegant in design.
