Cole,
Welcome and congrats on buying a tt!!!
It is great to see you asking questions before buying, unlike many who have learned after the fact in one way or another, myself included.
Best thing to do is start by figuring out exactly what your tv (tow vehicle) can safely tow, and more importantly, haul. By haul, I am referring to the payload of your tv as it was built. There is a yellow sticker in the drivers door jamb stating "Passengers and cargo not to exceed XXXXlbs". This is for your tv as it was built. The weight of the family, cargo (coolers, firewood, bikes, etc), the wdh (weight distribution hitch), AND the tw (tongue weight) of the trailer should not exceed this payload amount. Understand that any accessories added afterward need to be counted toward this amount: truck topper/cap, tonneau cover, step bars, bed liner, mud flaps, etc, all add up weight wise.
Knowing your payload and the tow rating will allow you to start shopping for a trailer. The manufacture "brochure dry weights" are almost a fantasy number. If you read some of the threads currently active about weight, you will learn that. The dry trailer weights often do not include options, some being "mandatory options". The dry tw (hitch weight) does not include the weight of the propane tanks or a battery on the tongue: 2-20lb tanks and a battery are ~120lbs, 2-30lb tanks and a battery are ~160lbs, added to the tw before you even load the trailer with food, pots and pans, clothes, bedding, chairs, grill, toys, etc..... Because of this some members suggest to use the gvwr of a trailer, and figure 13% tw based on the gvwr: example 7,000lb trailer gvwr, would be 910lb tw. They suggest this due to the tw generally needing to be between 12-15% of the loaded trailer weight for a safe, stable tow. And unless the trailer has very little cargo carrying capacity, most weekend/ short trip campers do not load their trailer to the gvwr. BUT on average it does seem the average person/camper adds about 1,000lbs to the trailer.
Our Jayco 32 BHDS has a "brochure weight" of 7,600lbs, with 920lbs tw (I think it is...). The yellow uvw sticker (every newer trailer has one) states it is just under 8,000lbs, but that does include the propane tanks, but not the battery, so just about 8,000lbs even with the battery. Loaded, ready to camp minus a few things (had just got the trailer, wasn't completely finished loading: bikes, rear frame mounted hitch for the bike rack, few other things) was about 8,700lbs with 1,400lbs tw. The weight adds up quickly!!! I figure with the rear hitch, bike rack, bikes,few other things added after weighing, and our boys stuff we are about 9,200lbs loaded now, will have to reweigh to get the exact tw again!
Make sure you get a good wdh!!!! The Reese HP Dual Cam, Equal-I-Zer 4 way system, and the Reese SC (very similar to the Equal-I-Zer, but offers more hitch head adjustment) are very good systems with integrated sway control. There is a couple stickies (Towing forum, and Tow Vehicles I think is where they are) that explain how a wdh works, and how adjusting the wdh to obtain the best tow as well. Even if the dealer sets up the wdh, it is for an empty trailer. Once you load the trailer you probably will need to readjust the wdh.
There is a fair amount of needed accessories as well, but once you decide on a trailer that fits your family and tv, we will be happy to help you become prepared if you need it!
As for manufactures, part of our decision to go with a Jayco was the 2yr warranty, and we liked most of the features. I have since learned if you purchase a Forest River (FR) product (they make many different brand names, search Forest River RV) you can add a second year to the warranty for $150. We may have looked closer at the Puma comparable to what we have had we know that. Not sure if it would have totally changed our mind though! I also read (anyone confirm this???) that if you go to the FR gathering at the factory they do repairs for free, even when out of warranty.... No idea if this is true, or to what extent of the repairs....
As mentioned, do not believe most salesman as to what your tv can safely tow!!!!
Good luck!!!
