So, there are 6 jack stands total. 4 in the rear, two in the front.

Sounds great James but I will not have the luxury of having the concrete floor and workshop. She's sitting outdoors, 300 miles away in a storage yard on grass with temps in my pick up window (late March) just above freezing. No power and the only tools and cribbing available will be what I drive out there with. Despite the less than optimal conditions, I have to change the 10+ year old tires one way or another.

I don't think I'll attempt to raise up the entire coach but I would like to do the rears in one go if possible.

Can you move it to concrete or pavement? Jacking and working on dirt is a real PITA.
I've hauled around patio stones plus thick plywood to put jacks and such on. Especially bad in spring.

Rob and I are getting a set of these spring bogie supports made up and we need to know the best length.

Some members suggest up to 13-1/2" inches or so but from reading various posts on the use, others think that's too long and would be difficult to remove. Some say no need to go any longer than 11" ...consensus/opinions?

Oh and after you've finished the job, when do you remove them? Before bringing the coach completely off the jack? When the wheels take the weight? After you air up the bag?

You can insert them just when the jack starts to take the weight on the bogie going up. After you lower the jack and the tires start taking the weight of the coach, lower a bit more and feel when the supports are loose. Then wiggle them out. I leave my bags aired up the entire time.

Mine is 16" x 2.5" x 3/8" thick. Not too long. I would go 7/16" thick next time.

Mine are 11” x 3” x 7/16”.
They work just fine.

I remove them when the wheels take the weight.

Bob Dunahugh told me that he had quite a bit of spring leafs and that he intended to cut them up to make inserts for jacking up the GMC and make them available for GMCers.
Anyone might want to contact Bob if they need them.

Don't EVEN use jackstands unless they're on concrete. I don't use them at all except for temporary support when I'm not going under the coach. I like 4x4 or 4x6 cribbing. Lots of it.

Wood will never fail you. A jack stand? Maybe. Even improperly placed wood
usually works fine.

Larry, I just recently moved 8 wheels and tires off a GMC SUV. I have a Dodge Grand Caravan Mini Van. I definitely
could tell that I had a bunch of weight in the van even though 4 of the wheels were factory steel and 4 were factory
Aluminum. You'll probably be surprised how big each tire and wheel assembly is and how much each one weighs. Make sure you use
at least a decent Mini Van or pick-up truck.

The shorter the bar the higher the coach must be jacked to get the wheels off the ground. I made a set from a pair of worn mower blades and glued on rubber spacers to make contact sooner.

I just had a conversation with Bob Dunahugh and while he's not posting, he's watching.
He's working to clean out his garage and has a few bogie bars for jacking up the rear of the coach.
$15 plus shipping till they're gone. If you're interested call him at 31NIne-52One-489ONE.
