Maybe...we need more information.
OP...let's check some of the obvious things...
Is the suspension in good shape on the fiver? And no, even if new..doesn't mean it's in good shape. Could be assembled incorrectly.
Are the brakes actually working on the fiver? My dad had a brake issue (no brakes) and he described a similar situation..said he could feel the hitch taking a lot of weight. Turns out he had zero brakes.
Are all the bolts on the pin box tight?
Tires on the TV and Fiver aired up to the correct psi?
Thanks!
