Keep an eye out for a used F-150 to lessen the blow. We got a killer deal on our 2015 last fall. It is in perfect condition, someone just had it until the warranty was up then traded it in.
But, we've been in your shoes before. When we bought our first TT toyhauler, we had a less than a year old 2013 F-150. We did a couple trips with it and felt unsafe so we ended up trading it in for an F-250 which made a world of difference. The good thing about lower mileage newer trucks, their trade in values are still pretty good, unlike cars. We've never had to trade in a truck that was underwater.
