60W is pretty small for most practical purposes. I'm not familiar with your TT, but, generally, solar-ready means the wiring is in place for roof mounted panels. If it has a port in the side for a portable panel, I'd consider getting at least 100W and maybe 200W. Renogy makes some reasonably priced options, here's a link to the 100W panel. Note that rigid, rooftop panels cost about half as much, but without a controller. A properly sized controller can handle several panels.

If you have a side panel port, you'll need to confirm it matches the polarity of the portable panel before plugging anything in. If not, you'll need an adapter.
Roof-mounted panels have the advantage of always being deployed and working, whether your TT is in outside storage, traveling down the road, etc. Their main downside is they don't work well in the shade and we like shady camping spots.
Portable panels can be set up for optimal sun exposure but they need to be set up first. They're also subject to theft when you're away from your campsite.
Many consider the optimal set-up is to have several hundred watts of rooftop panels plus a portable panel to optimize exposure in shady spots when in camp.
If you bought this from Amazon and can still return it, I recommending doing so until you're more educated on the topic. There are a lot of applicable threads on Winnieowners. While educating yourself, you'll also learn about improving your battery bank. The single 100 amp hour dual purpose Marine/RV battery isn't up to the task.
