Welcome to the forum.
I always recommend RVupgrades for a lot of things but especially for wiper blades as they have an excellent selection of WiperTechnologies (Diesel Equipment) inventory. They are slightly more expensive than what you'd buy at Walmart or the local auto parts store but WT blades are heavy-duty and well constructed.
The Wiper Technologies catalog lists a WT8-32 for a 2014 Tuscany. However, that is a J-hook ...go HERE
The same blade without the J-hook mount is the WT6-32 ...go HERE

They are the same price and both are in stock.
Since we are allowed to recommend forum sponsors, I highly endorse RVupgrades as they are a forum sponsor and its owner is the founder of the iRV2 forums. From my own experince, they are the best online vendor for RV accessories. Excellent customer service, fast shipping, and a vast inventory.
