'open topped' really does hurt the penitent engines as even S5/6 weapons will immobilise or destroy you 50% of the time on a glancing hit... penetrating hits means you're a gonner! (you have only a 1 in 6 chance of surviving a penetrating hit!)
maybe try and use either a chimera or a rhino for some mobile cover? all vehicles are size 3 (though admitidly, land raiders can be argued to be size 4!)... however, blocking your opponent's line of sight is always recommended!
also don't forget about your 'holy rage' rolls! i've seen a penitent engine move 15-18" into assault in a single turn...
hope this helps,
cheers!
