Welcome and congrats on the rig if you go for it!!!
The biggest obstacle for a 1500 is the available payload. There is a yellow sticker in the drivers door jamb of your truck,l stating "All passengers and cargo not to exceed XXXXlbs". What is the amount? As stated, all passengers, all cargo: coolers/bikes/firewood/etc, the wdh, and the tt tw (travel trailer tongue weight) should not exceed that weight. How much does the normal passengers weigh, and what cargo do you anticipate hauling in the bed weight wise?
The "brochure" dry weights are only a starting figure. The dry tw does not include the propane tanks or a battery on the tongue, which add about 120lbs for 2-20lb tanks and a battery, or 160lbs for 2-30lb tanks and a battery. That is even before loading the trailer up with your "stuff".
Look into a good wdh with integrated sway control. The Reese Dual Cam, Reese SC, and the Equal-I-Zer 4 way system are all very good for the money. You will probably need to readjust the wdh once you load the trailer up for a trip. The dealer is only setting up the wdh for an empty trailer. Follow the links in my signature for a ton of info regarding the wdh.
Look in your glovebox on the RPO codes for the axle ratio you have. Do a google search for the Silverado gear ratio codes to match it up. Will be a GXX code. On my phone, and can't try to find it at the moment, sorry.
