As I search the internet I see many people offering custom grill covets.

Can anyone make any recommendations as to who makes great covers?

Vinyl Coverings by Mel.
I get all my covers from her.
Last forever (well maybe not forever but a long time)

+1 on Mel.

They're heavy, but your grandchildren will be using it.

+2 on Mel, excellent quality and priced reasonably for custom.

I hate to post when I don't have anything new to add but one more vote for Mel.

I Purchashed one from MAk grills five or six years ago and it has held up very well in all types of condition so my recommendation is to see what materials they use and buy one similar

As an update, Mel had shut down for the pandemic, but has reopened.
I had ordered covers (emailed her Visio drawings) for my outdoor kitchen when she was shut down.
She was nice enough to email me back an let me know about the situation and put my order in the queue.

Thanks all.
