The Ultimate Support USHB2-KB61-GR looks great! It even comes up on Walmart.com. DNJ... did you use this case with you Pa4X?!?

The inner dimensions are 40" x 14" x 4"...
+1.42" longer
-0.35" not deep enough
-0.94" not tall enough

Looks like it should fit!
$179 for a bag case?!?

Shipping weight is 5.8 lbs... so it will only add a little weight! It should be worth the price over the next 6 years (2023) of moving the Pa4X.
