Hopefully you are getting a weight distributing hitch (WDH) which will make towing a lot safer and less stressful. That dry weight on the TT doesn't mean much, get it weighed at a truck stop. You are pushing the truck payload possibly but should be OK.
Since you had a class C you know all about the paraphernalia that you'll need. Sewer and water hoses and so on.
Before you pickup that TT get a good RV Inspection Checklist:
Checklist
There are many and that's just one that popped up on Google search you may want to look at others. Catch the problems before you drive it off the lot, which is when you have the most power over the dealer.
