I had one on our previous Rockwood MiniLite. If I revert back to travel trailer from the current 5th wheel I would use one again.
Can it be used in the folded position in those cases ??Yes I have used them on my past two travel trailers. They give you extra height up front on the tongue and requires less jacking to achieve needed height. The only downside is every once in awhile it is too high at minimum down and locked position for some campsites, requiring its temporary removal to get front of trailer lower.
What was your hitch weight ?? Mine is 900 lbs.I had one on my last trailer. Very handy but the pin that it pivots on wasn’t heavy enough. It bent and then didn’t operate very smoothly.
