Intermodal for first job?

Hello to all. I've been a lurker on here for a while now and just wanted to say this place has been a GREAT tool for helping me get some valuable insight and gain some needed perspective about the industry as I'm entering the field. TR has helped me alot with planning and direction. I appreciate this forum and all those that are here on the regular helping newbs. THANK YOU!! I am 54, changing careers into truck driving. I finished school thru my local community college (grant funded) and I got my CDL A last week. I also have my TWIC and X endorsment. My goal is to drive hazmat tanker and/or dry bulk with a company here in Columbia SC but need experience first. I had my first interview today with a company hauling containers home daily. They have a student training/mentoring program for the first month or so and pay would be $18 per hour during that time but then jump to 52cts mi and 25$ per hour non driving once I pass training and get cut loose. The terminal manager spoke very highly of the trainers and their experience. Also he said that the training would be quite intensive and very safety focused. I'm interested in all that, I want good training and to be a safe driver. Now the part I'm not so sure about...I would be starting on the night shift which I think I can handle alright, BUT many of their lanes are going through the mountains of western NC and eastern TN. Heavy loads and winding roads. At night. The night shift would be terminal to terminal and all drop/hook which is good I think, but im a little sketched on the heavy haul in the mountains. The company I eventually want to work for said after six months and they'd consider bringing me on so if all went well I could be looking at till the end of summer then moving on. Does this sound like a good move to get on doing intermodal for first gig and to gain my much needed experience?
