I'm thinking the solution to my problem is to replace my current jack with one with a wheel that either will fold up completely or will raise higher than the one currently installed.
The weight of my trailer is 1890 lbs. Not sure what the tongue weight is.
All the jacks have weights associated with them. Is that the maxmium tongue weight?
Should I have a jack with our without a wheel? one that swings back or one that raises. It seems like the swing one might not work on my setup due to the frame

These look like possible choices, but I'm not really sure.

Also I don't know how to weld so I would prefer that I not have to have it welded on unless it's better to do so. I have a grinder so I know I can take the old one off ok.
Thanks in advance
