I will be able to squeeze out the game completion achievement leaving the two gold medal achievements. I attempted both the time and water limit trials on the van and failed miserably. I will continue with more attempts but do find this aspect of the achievement gathering, trying.
Props to you. I'm still going to end up adding quite a few hours to mine.
