We bought our NTU 2007 Fleetwood Niagara for really cheap. We have taken it out once and love it. We didn't research before hand and didn't realize we only get 600 lbs of cargo including water. I've been searching the internet and found that the axle they put on this PUP isn't ideal for the trailer weight and people are having major issues. We are supposed to take it on a long trip to the Oregon cost this summer and I am really nervous about having issues on the road. Obviously we'll get the tires looked at before we go, but would it be worth putting a bigger axle on it? Any idea how much something like that costs? I know we'd have to buy the axle, springs, new stabilizers because of the height change, etc. Anyone have any insight or advice? Thank you!
