I think most of the time we get a precursor leak before a hose blows. So I think a frequent inspection will keep you out of trouble. Some of the hoses can be difficult to remove/replace ... so don't wait until some inconvenient event occurs, and you find some trip disrupted.
I would recommend replacing all hoses at one time when you do replace. In that regard, you might begin seeing how many of your hoses are readily available at the "aftermarkets". Make a list of their part nos. Buy ahead any preformed hoses that are hard to find. Don't overlook any that feed the rear heater.
Be prepared to deal with the quick-disconnects (may not exist on your model) that are used on some systems.. Repair kits are available for these. I nearly let a quick-disconnect ruin my '99 3.8.
Have a rotary tool and cut-off wheel ready for removing some of those factory clamps ... it's the "best way" sometimes.
