Rack recommendations

We just got a new (used) mini-van and I am not too keen to transfer my Bauer Revolution from the old van. I have 2 main complaints about it. One, it’s very heavy and I’m the only one in the family that can handle it, at least for the next couple years. Two, It doesn’t hold odd shaped top tubes so it’s a pain with my kids’ mountain bikes with oval tubes. My criteria for a new rack are:

Hold 4 bikes, with various tube shapes

Hitch mount cuz a roof mount on top of a van is unwieldy and I know my wife (or I) will drive it into an overhang with bikes on at some point

Swing away feature

Lockable

Have ski rack conversion

Not too heavy

What do you have that you love and think I will too?

I do like the rack but will my wife be able to handle it?
