I purchased Casita
2nd hand, and have been on a few trips so far.
One of the things I noticed, is that the jacks do not hold the weight
very well, and tend to slip if weight
is applied to them. The trailer/jacks are fairly new (2016), so it seems to be a design issue.
The jacks seem to slip often whenever you put a little extra weight
on them (e.g. a 200lb+ man puts his weight on the step).
The jacks do have holes in them, and I used clips from the tow pins to prevent them from slipping, but wondered if anybody has used anything else or has other suggestions.
