Do I need to ground my generator?

Question

I have a portable generator with bonded neutral. I have connected it to my main panel via 50 amp inlet and breaker (yes, I installed an interlock). The neutral and ground from the inlet are connected to the neutral and ground bus in the main panel, respectively. The question is, do I need to ground my generator separately? My guess is no, but that means I'm bonded on both the generator and in the panel which I've read you don't want to do. Please advise.

50 amps - thats a huge portable generator
I connected mine, with an interlock but its only 30 amp
I never put a ground to the generator, I haven’t had a problem during outages
I used an RV outlet to feed the main and a 30 amp rated extension cord to go between the two
I did clear a spot and put patio pavers down where the generator goes because the heat from the motor killed the grass

What you need to do is DISCONNECT and DESTROY the "suicide cable" you used to connect the generator to house wiring. Then hire someone with a CLUE to explain to you why if you want to tie into permanent wiring, your FIRST step is to replace the generator with one designed to be HARDWIRED through a transfer switch.

Note: There is literally NO SUCH THING as a 50 amp, or ANY amp, 'inlet' to the panel. Even if your main breaker is 50 amp, small by today's standards, that term is PROOF you are 100% unqualified to replace a light switch, much less screw around with the main panel.

What is clear is YOU DON'T HAVE a basic understanding of either electricity OR English. I have a grip. YOU need therapy.
