Hi Rob,
Your T2363, is it a 1999 model year camper?
Assuming it is, a 99 T2363 has an empty camper "dry" tongue weight of 520#. When you add the battery, LP gas and camping gear in the camper, the "loaded" tongue weight I would estimate to be 700# range. The only way to know for sure, is to load it and then weigh it.
At some Sunline Meet and Greets over the years, I would offer members to weigh their tongue weight. This post lists some of those campers.

The 2, T2363's that I did weigh came in around 650# loaded with the gear they had.
We need to know a range of what the loaded tongue weight could be so we can select a closer match on the sizing of the weight distribution hitch and spring bars. We also do not want to size the WD hitch spring bars too strong as that can create a harsh ride and in some cases and damage the trailer A frame which has happened before.
I'm going to suggest a spring bar rating of 750 to 800# as a place to start. This lets us start to size up a WD hitch and narrow down the brands.
Next comes features of the WD hitch and what might be important to you. As far the weight distribution (WD) part of the hitch, there are lots of choices to pick from. On a travel trailer the size of yours, a WD hitch that has an anti sway control feature is a recommended thing to have. The anti sway helps when bad towing days happen such as, high cross winds, fast panic manoeuvres due to other motorists, potholes etc. Some brands have integrated anti sway control others have add on features.
If you happen to have brand of WD hitch in mind that you have heard about, we can discuss them and see if they will mate well on a Sunline T2363.
I'll make a few suggestions and we can go from here. Knowing the T2363, it is a low tongue height camper. Trailer ball height pending model year can be in the 16" range. Meaning the tow ball is down there (lower to the ground) compared to other brands and style of camper. And a lot of standard WD hitch packages offer a somewhat standard hitch shank. It may mean you have to buy a separate longer WD shank. On your Chevy, assuming you have the standard GM truck receiver, you will need a drop shank to lower the hitch head down so the camper will tow level. Most likely a 6" drop shank but we have to check that. Towing level is a need to help make a stable camper and to load the trailer axles more even. A lot of nose high or nose down towing is not good.
I happen to have some pics of 2007 T2363 hitched to a Silverado most likely similar to yours. The truck maybe not as new as yours. This is a Reese 800# rated trunnion style WD hitch with the Dual cam anti sway. It is the best Reese makes for anti sway. The trunnion style hitch does not hang down as far as the round bar style and will help on setup.
And the names of some of the parts
Reese also offers that same trunnion style hitch with an add on friction anti sway bar. It looks like this
The add on friction sway bar system is offered by several other brands too. The add on single friction sway bar regardless of brand, is the basic anti sway control. It does help but does not work as well as the integrated hitches with
anti sway built in or if they had double friction bars.
Another brand hitch that comes in the 800# spring bar range trunnion bar that has integrated anti sway is the Fastway E2 WD hitch. This one

They offer the trunnion style as well.
And another brand that comes in 800# spring bars, trunnion with integrated anti sway is the Husky Centerline TS. I'm recommend the TS part as they do offer Centerline version that has springs in the hitch head and is not the TS version.

Those are some of the WD hitches that would work on your camper. I myself prefer the Reese with the DC for a few reasons. The Reese trunnion style WD hitch comes in 600, 800, 1,200, 1,500 and 1,700# spring bar ratings all using the same WD hitch head and some other parts of the hitch system. That means I can upgrade the bars if I get a larger camper some day and not have to replace the entire hitch.
The Reese trunnion bar head has a serrated washer fine adjustment to it that I prefer over the changing of washer spacers many of the other brands have. Reese has a lifetime warranty on their hitches. The Reese Dual cam is the most effective of any of the hitches I linked above in anti sway performance. However, to be fair, it does take more effort to set the hitch up at first. Once set, it is not a problem. It is a trade off of effectiveness verses setup time.
I can link in places that sell all of those hitches and help you size up the correct hitch shank if wanted, once you have time to review this and sort out which you think would be best for you.
Hope this helps, ask away on any and all questions. Taking the time to sort this out in advance and learn about your WD hitch, will pay off big time in years to come towing a camper.
