Want input in executing "Plan Bus"

[mcowenae]

I am in the early stages of starting my Skoolie to move into full time with my wife and 2 young kids. So far I have found two, that seem like good buses I would love thoughts, and input both are transit style and blue birds and early 2000's.

Option 1 is a full 84 seat 40', it is a front engine style 5.9 cummins with Alison 3060
Issues are Electrical gremlins in the panel and gauges
good are it is less than 200K miles.

Option 2 is a 75 seat so less than 40' Rear Engine 8.3 cummins and Alison 3066
Issues are 300Kish miles and it is smaller.

what are everyones thoughts, I do not plan on driving a ton but I would like the power because I am hoping to Tow a minivan at least sometimes and would like to not be struggling if my journey takes me back west I do not want to struggle in the Rockies or the Cascades. I am leaning toward Option 2 pretty heavy am I missing something? my only reservation is the miles on #2 or is that not a concern I should have?

I would like the space, but the Gremlins combined with it being a FE and 5.9 have influenced my thoughts and opinion the most.

Am I totally of base? What are everyones thoughts?
