I have a 2018 Phoenix 21 PHX w/ Marine Master dual axle trailer. It is a low profile trailer. Would like to know how many on here have had issues with trailer springs as this is my first time with this type of break down? Recently, on a fishing trip I had a broken spring. Got it fixed. Maybe I went overboard a little, but in my mind, when is the next ones going to go. So, I've had them all replaced. The question I am asking is, if this has happened to you, How long did it take to change them all out? From the time you started taking the old ones off to the new ones were back on. Weather or not you done the job or had someone do it for you.
