Diesels have electronics just like petrols so much of a muchness.
Generally only an issue if you don't prepare the vehicle for the crossing or get stuck. Avoid water like the plague - 4wds are not submarines and water stuffs lots of mechanicals.
You are on the right track with a petrol patrol or landcruiser. There are some great bargains out there. For my money it would be a stock 4.8 patrol and I would add a snorkel, Bilsteins and king springs.
Sequential LPG if you are doing more than 20k a year.
Forget bar work unless you can't drive. LOL. keep an eye out for front and rear factory bumpers to match the car and put them in the shed if u do crunch one.
Replace the side steps with sliders when u crunch one.
I had a 100series 4.5 petrol manual with a 2" ARB lift and loved it. Patrol is stronger in the drive line so is stronger but is yrs behind in noise vibration harshness.
Have fun.
