Question:
Ive been looking at the https://www.etrailer.com/Trailer-Jack/Stillwell/ST73FR.html. Is the bolt-on bracket adjustable for different trailer frames? Wondering if this is for bumper pull or a goosneeck/5th wheel

Hey Jolisa,
The bolt on bracket on this jack is not adjustable. It is a 8" wide x 7" tall bracket with 2" between each mounting hole. This jack is great option for any 5th wheel, gooseneck, dump trailers or any hauler. As long as you have a place for the mounting bracket to fit this is going to work for you.
What kind of trailer are you putting this on? Was there a certain size mounting bracket you needed?
