1985 Allegro

[happyboy1]

We just purchased a Allegro rig. It has been sitting for a while and needs some love I am looking for a Chassis manual . Where do I find a data plate? I do not know the model. Any help would be appreciated. Thanks

Can you tell us which engine it has in it?

It has a 454. I understand that it is a GM chassis . Not sure what size
How do I measure the length of the camper is it just the box or from bumper to bumper? Thanks again

It will be a Chevrolet P30 / P32 chassis, service manual sets are commonly available on ebay for $20-$30, most of the sets I have seen are for mid to late 90's models, though. Search P30 or P32 chevrolet manuals on ebay with the condition being used you will find hundreds of them.
