I use a double-bow soft case. Classic accessories maybe? Has straps to attach it to the roll bar. Keeps it legal where your bow needs to be in a case.
I use the same case. Have to treat the zippers with some kindness when they get dusty but it’s great. In its fourth season now and still going strong. Has separate pockets for quivers and two bows. Did pull one piece of foam out to make a little extra room inside.
