Depends..on an F150 I'd probably get them.
What they do is spread the tongue weight to the front axle - so you can do the math and decide if it's needed or not.
Figure 10-15% of LOADED trailer should be on the tongue/hitch so if the TT is 5500 loaded that's 825lbs...if the TT is 6500 its close to 1000. Add anything into your bed, plus the hitch weight and you can be pushing the limits (with passengers) on the GVWR. Since most is in the back the front of the truck goes up..harder on the truck, scarier steering, headlights point at the sky, etc.
You buy it once - you use it everytime you camp and it can be moved from TT to TT so you'l have it for life.
I got ones with anti-sway built in and it's amazing - wind, passing trucks, uneven pavement and no sway, no issues at all. Steady as she goes.
