Sunvoyager shift panel and dash gauges not working

[sooner than later camper]

Hello all!
We just inherited a 1999 Sunvoyager. Not sure of the model beyond that at the moment. We just put new batteries in it and it started like a champ! However, the dash gauges are not working and, when attempting to put it in gear, the panel isn't registering any life- no lights, doesn't work etc.
Could this be a fuse problem since both areas aren't working and, if so, where would be the fuse box be for this issue?
The manuals we have are not the best.
Any help is greatly appreciated. This is is very nice and only has about 21,000 miles on it. Trying to get it running to sell in the very near future.
