Can a WD hitch be hitched at a vertical angle?

One caution. NEVER (IMHO) try to attach or remove WD bars if the TV and TT are in a "V" configuration. (opposite of your picture). In that case the bars can be under VERY high tension, enough to make it dangerous to remove. The cheater bar can get away from you and be bad new.
