When a trailer is towed often, the grease gets circulated and warmed up.
This helps prevent condensation build up in the hubs and keeps the grease stirred up.
Moisture can cause rust which can cause spalling over time.
Especially on larger trailers, extended setting in one spot can actually stress the bearings just from the weight
The word Extended is not precise but it would mean more than a few months, depending on the conditions of storage.
Typically , for instance a utility trailer which has been left outside in the yard and exposed to the elements without being used for more than a year sometimes longer is likely to suffer some damage, which will accumulate over several storage periods.
suffer from long term parking as well for some of the same reasons.
If you have good storage for your Fiberglass camper and use it a few times a year , then sitting is not generally an issue.
