We own a 35ft Itasca Sunova - bunk bed model. Workhorse gasoline engine - 2008.
We really enjoy the RV, make occasional trips with our family.
Problems have been few - however the most troubling is the charging system...it seems the house batteries don't always charge while driving...
House batteries in general seem to be a struggle - how to care for them during storage.
We find RV-ing confined to a park with electric hookups for overnight to be a bit limiting - trips often are better served by spending a brief night in a rest area or Wal-Mart parking lot. However, all dead batteries in the morning is a little discouraging.
Otherwise - we enjoy traveling in our RV very much.
