The is much written about bags and springs in the Chevrolet Motorhome Chassis Service Guide.

I think the hardest part for me was getting the old bags out!

Even if I did install upgraded springs I think I would spend the extra $100 and install the airbags while you had it apart. Just in case the heavier springs didnt do what you thought they might. It would be so easy and youd have your rear end covered.

In my AS manual it shows inter-spring bags and over spring-shocks. These front ends are very overloaded.
I also see Heavy duty spring is for Weight Rating for this Kit - 5,700lbs.
And Extra heavy duty spring is for Weight Rating for this Kit - 7,200lbs
Better get the front end on a scale before I pick.
If I'm going to take the front end apart I will do the springs and pass on the bags.
Putting the bag in hot water does sound like a good idea.

I used air lift from Amazon as well. I found that getting the old ones out took 90% of the time, and I'm not sure what I'd do differently. Vice grips and brute force twisting and pulling. When I installed the new ones, I removed the cap and flattened them between two pieces of plywood in my vise, put the cap back on to hold the vacuum, then folded it in half and wrapped with a big hose clamp. Went in pretty easy. Just don't forget the reinforcing rings at top and bottom.
