Not real familiar with that specific model, but the tv is overpriced. You can buy a better one for cheaper at BB.
The bumper mount grill is pricey. Some like it, some don't. If your in the "Famous" Flint, I have a bumper mount grill I will sell for cheaper than the factory option.
I would suggest the factory option rear cargo hitch if available for that model. We carry 4 bikes without any issues so far. You could carry a small generator as well. It's rated for 300lbs if I remember right.
Get a good wdh with integrated sway control!!! The Reese Dual Cam, Reese SC, or the Equal-I-Zer 4 way system are all very good for the price. If you choose the Dual Cam, make sure the dealer knows not to set it up right.
Verify you have enough truck before ordering/buying!!!! Last thing you want to find out is you are over the trucks payload or rear axle rating. What tv (tow vehicle) do you have? There is a yellow sticker in the drivers door jamb stating "All occupants and cargo not to exceed XXXXlbs". What is this amount? This amount as stated, includes all passengers, cargo (coolers, bikes, firewood,etc), any accessories added (truck topper/ tonneau cover, step bars, etc), the wdh, AND the tt tw (travel trailer tongue weight).
What are the listed weights of the trailer? The "brochure" dry tw (tongue/ hitch weight) does. It include the propane tanks or a battery weight on the tongue. For 2-30lb tanks and a battery that adds ~160lbs before even loading the trailer with anything else for a trip.
Compare the total family weight, anticipated tv cargo weight, the wdh, and see what is left for the tt tw. You generally need 12-15% of the loaded trailer weight for tw for a safe, stable tow. It seems most add close to 1000lbs to the trailer, some more, some less.
