There's a big metal tank where the spare wheel goes, so you lose a bit of space. Availability can be a problem occasionally, particularly where I moved to, but filling is just as easy as filling a petrol tank.

In theory the engine makes a bit less power flat out, but I never drive flat out. It's quieter, runs cooler and cleaner, and has a bit more low end torque because propane burns with a bigger slower bang.
