Great idea on looking for a combo setup from someone finished with traveling--a little looking a RV forums in the classified sections, RV trader.com and such often have complete setups ready to go.
Otherwise, I would think FIRST is to figure out which fiver (size, model, etc) you would like. Once that is known, you will need the Gross Vehicle Weight Rating (GVWR) of that unit, take 20% for the pin weight (PW) that is placed on the tow vehicle rear axle. With those two numbers, you can begin to thin down the options for a tow vehicle.
Please DO NOT use a mfg's listed 'Dry Weight' and 'Pin Weight' as actual weights--they are notorious for being optimistically light on these numbers.
It's a confusing world out there and easy to buy wrong tow vehicle, or end up with a trailer that is way heavier than you thought after loading it.
Good luck, have fun with the search.
And, welcome to the forum.
