Yes. Upgrade all leaf spring packs to their next size up. re: +1 up size. I would - without hesitation..
To validate +1 upgrade isn't too much, simply take trailer's GVWR, divide by 4 (assume 4 x wheel hubs) and round up to the nearest available size. If you load heavy and/or tow on bumpy roads, then round up +1 more - for extra safety buffer. This works for me.
When you have more dollars in future, then upgrade its other moving parts - like shackle plates, worn out bolts, etc. And if possible, upgrade to wet bolt system.
Hope this helps.
