A frame bike rack

Hello, I`m looking into a new bike rack system. my 4 bike on the rear works well, its just a pain getting them mounted solidly and then trying to access the rear storage compartment.

I found this one, Arvika 4 bike system. it looks well made and very solidly mounted. I`m not worried about excess tongue weight, I can move things around to offset that. wondering if anyone has used this one or anything similar and how it is working for you.
