I have looked into them extensively and think they may have some advantages due to being able to split gear changes. This would be advantages for your 4 speed transmission. With ratios using a GV being:
1 : 2.48
GV:1.93
2 : 1.48
GV:1.15
3 : 1.00
GV: .78
OD: .75
Double OD: .59
You can quickly see that 2nd gear in GVOD would give you a 1.15 ratio and about a 15% increase in towing power on long grades that you can't now pull in direcr (3rd gear). If the hill is steeper you would then turn the GV off and drop into 2nd gear 1.48 ratio.
About $4000 if installed by yourself or an additional $500 for labor. Rear driveshaft would need to be shortened @ about $200
