If you have a v-tailgate and dont need to open the gate while hitched then yes straight down is the best way to go as it will remove most of the stress off the pin box frame and most likely eliminate any chance of frame flex or breakage.

Extended pin boxes are for those that want to tow a 5er without a sliding hitch!
Puts the nose further back when turning with a SB, that and radically rounded fronts, means non slider SB towers, just need to turn a bit further to dent the cab and bust a rear window.

Now we all get chopped up front closets because of it. we still enjoy a 8' wide flat floor in our 5er.
