Unless you are willing to throw money at it, most likely it will be a pain in the rear. Far too many times the setup isn't right and then you'll be smelling propane all day. No, this is not a happy smell and in general is quite dismal.
Also propane always runs out at the most inconvenient times. Like say, during a hill climb and you have to ask some random guy to "climb in there and switch tanks while I hold the brake pedal". Yeah, that sucks if you are the guy swapping the tanks. Or when you leave your spare tank at the tow rig and while at the farthest point away, guess what happens.
Overall, I'm fairly negative on the subject just from experience. Smelling that stuff all day and wondering when the tank is gonna run out really isn't all that fun. I believe Clippa has a similar story.
You already have EFI, stick with it. Except for needing another vehicle to go fill up your fuel tank...during normal business hours...you won't notice a difference.
