AC Delco site (http://parts-catalog.acdelco.com/catalog/catalog_search.php) says original engine battery size was Group 78 (670 to 800 CCA ranges).  Delco P/N 78-7YR

Winnebago brochure (http://www.winnebagoind.com/products/previous-models/1990/pdfs/winnebago/90-Chieftain-bro.pdf) says it was only a 630 CCA battery

I do not see battery size in parts book (http://www.winnebagoind.com/service/wincd/1990/90wcfm31rq.pdf)

Choices will depend on how much room you have left in the battery compartment.
