Questions about 2015 154BH

[MoTx]

Hey all, this forum has been a great resource about Jayco TTs, thanks for everything!

I'm in the military and we're moving from Oklahoma to Alaska in around 6 weeks and we decided to drive up through Canada. Instead of having to deal with hotels, we've settled on a 2015 154bh we'll be pulling with my 2001 5.4L V8 F-150.

Our Camping World should get a new 154bh in next week sometime, so I've got a couple questions.

1. Is there an external Cable TV outlet? If not, is the dealer putting one in a big deal?
2. What do I absolutely need to get added? Stabilizers, type of battery, etc? I'm a newbie...
3. Is there anything Jayco has done different to "fix" any annoyances of the 2013/2014 model?
4. Anything else you guys could provide would be great.

Thanks!
