Hey Nick. To connect your 30 amp Generac i3500 generator to your trailer's 50 amp male plug you'll need the Mighty Cord RV Power Cord Generator Adapter item # A10-G30350VP. It has a female end that will connect to your RV's 50 amp plug and male end with a a 3-prong twist lock that will go into your generator.

My male on the trailer is a triple blade as well. So that won’t work. Do you an email where I can send you pictures?

@NickM You can email any pictures you have directly to the address you receive this response from. I'll be happy to take a look at them. I was hoping that was a typo on the 50 amp 3 prong because all our female 50 amp adapters are 4 prong and rated for RV use.

It is a must have if you own an RV. You never know what type of outlets campgrounds have.

I bought this as an adapter to go from my i3200 generac generator to my plug in soft start. My travel trailer is 30 amp.I didn’t want to void warranty on ac by installing a soft start on ac unit. This generator to 50 amp adapter works great, never gets hot, male and female ends look and feel well constructed. I would buy it again if needed.
