Diesel Vs. Propane Vs. Gas - HDJ81 Vs. Suburban

I just cut and pasted my post from a Land Cruiser Site I'm on. New to Suburbans, main concern in reliability. Already hear the Burbs diesels have some serious weak spots????

Ok, so I've pretty much concluded that at the moment I can't afford a nice HDJ81, although I can probably get a cheap one, but the chance of ending up with a POS is too great for me to risk.

Now I'm looking at Suburbans (http://forum.ih8mud.com/showthread.php?p=2387948#), mainly because of they're size (Perfect for Surf trips, and I was always worried about the smaller HDJ81's), but I also can't afford to run around town in a big heavy beast with a 350 gas guzzler. The vehicle needs to be pretty much a daily driver

I'm thinking about putting propane in a Suburban (http://forum.ih8mud.com/showthread.php?p=2387948#). I've also come across a diesel Suburban, although I know they still get ****ty mileage too, especially compared to a hdj81, but at least I can convert to bio diesel or the sort.

The real reason I got hooked on diesel was because of the mileage figures I was seeing with the HDJ81's and the ability to run alternate diesel. Also the reliability of diesel engines (http://forum.ih8mud.com/showthread.php?p=2387948#) (I hear toyota diesels are the best? what about the ones in suburbans?) Also the fact that there is no ignition is nice to know when fjording rivers.

So I guess, if it comes down to a suburban, would I be better off with a diesel or dual gas/propane setup?

Also, how are the Suburbans for 4x4? I'm no rock crawler, but I want to do more surf adventures exploring coasts and down to Mexico, so mainly sand and mud crossing rivers. No real mountain crawling.

All thoughts and ideas appreciated
