Hello, I purchased a 2000 Journey 36L. It is the same as yours except for the floor layout and I have the Cummins engine. Anyway I took the Drivers Class that LazyDays has, on a DP like ours I think he said we are in the 50 55 degee cut. I think the thing to remember is when making a right turn, don't start to turn your wheel until your hips are even with the corner of the turn and then you can turn. This way your rear tires should miss the curb. This is my first MH and I have found some good sites that will help me in my driving. Here is one that might help you, I've found it very helpful.

Good luck!
