Thanks - good feedback... Are you planning on putting extra holes in the mudstuff locker for the additional vents? It seems that the Nak' locker is considerably more expensive and is going to be special order, so maybe the mud one is going to be quicker/easier if it's easy enough to add the extra vents in...

Any thoughts on why both of them blow air to the rear - is it because most people want to heat the back for camping etc, rather than any kind of technical requirement?

Yes, new holes to be cut. I may replace the front panel (has a grill in the panel).

It does seem odd that something specifically designed for a car that has a heater would blow warn air backwards, I need it on my feet

But swung the heater 180 degrees so it blows out the front. Fundamentally because I can’t stand cold feet (not because my amps are in the way )I rotated the locker 180 degrees also to utilise the vent hole.

Thanks - that's perfect, as you've confirmed that the heater itself works if you mount it blowing forwards which is what I'd want...

It sounds like a combination approach of mounting it facing forwards with some vents to direct the warm air where needed will work a treat
