The FW library no longer has brochures/flyers on any of their towable lines since they divested themselves of those a few years back. So, unfortunately, the link Ron gave you won't get you what you need since it's to the motorhome relations department. The brochures/flyers for the TT itself don't have much anyway, unless you're wanting floorplans or vehicle specifications (weights, lengths tank capacities...etc) & most of that can be found in stickers located inside your TT. Check inside kitchen cabinet or bedroom wardrobe.
The manuals that you would've gotten with your TT are for systems & appliances found in any RV.
HERE's a website that has many manuals available for downloading. You can also try putting in the name of the item you are looking for in an internet search & see what comes up (i.e. Onan generator manual).
