DwnSth, many thanks for the info. NO, won't find a diesel 250 for comparable $$ but the gas 6.2 can be , and that would be my target. Less worried about going up than coming down. That remains the crux for me I think. How well does the EB engine brake on downhills? The next consideration is weighing the 2017 improvements relative to the deep discounts with employee pricing right now. I understand that the SCrew in the 250 is actually smaller than the 150 but that will change this year. Thought the back seat of the 150 was cavernous to begin with, and certainly bigger than the back seat of my current TV so not a concern really. Sales guy is trying to dissuade from the 250. NO idea why ( but I do have theories)and I could care less. I will decide based on my needs and expectations.
