Nearly every bass angler starts off with 1 rod and reel plus a few lures. Today multiple rods and reel combination seem to be the norm, in reality you can only fish 1 at a time.
When you go fish lakes for the first time take the rod and reel combo you catch the most fish with. Today you can research fish reports for nearly any lake in the country and determine what the locals are using to catch bass. You more than likely have something that will work, if not buy it locally when you get there.
I traveled all over the country on business trips and only used 1 bait casting outfit and a small tackle bag, caught lots of bass everywhere using Texas rigged worms and jigs.
My tackle bag had 12 lb Big Game mono, needle nose pliers, sun screen, small flat file, 3/0 worm hooks, 3/16 oz planted bullet weights, 6" straight tail and 7 1/2" ribbon tail worms, 7/16 oz jig and #11 pork frog, all in purple and brown colors. If I needed anything else I would buy it locally.

PS, today you couldn't take that bag on a airplane!
