My 71 has a bathroom counter which I believe is ABS. I know it is not fiberglass. It has cracks which so far I have not been able to fix. I fiberglassed and screwed the counter to a plywood base to stabilize it and have tried to fix the cracks with polyester resin, bondo, 2 part epoxy paint, other paint, and superglue and the cracks magically reappear. My hypothesis is the ABS plastic has a high coefficient of thermal expansion. In other words, the stuff expands and contracts with the temperature but the cracks don't.
I could cut out a formica insert and attach it to the top serface.
I also am considering covering the whole counter surface with wood veneer. That would require bending the veneer around the curved edges where the top transitions to the side. I have never worked with veneer. Do you think this will work?
Also I need to replace the plastic trim on the counter. The "edge nosing" is available from Inland but I don't know if the inserts that snap into the extruded aluminum frame is available. Any alternative suggestions? Formica?

Curious that you have this problem today. I have noticed the same type of cracks in my bathroom. I have all of the aluminum trim and inserts but damaged one slightly removing it to reach the rivets for removal. I will try for a quick repair but if that doesn't work, I am going to make a laminated counter similar to the cook are out of 3/4 in plywood and laminate of my choice. In my last trailer, I tried to repair and finally had a friend who worked making boats in Tarpon Springs, FL make a mold of the old counter and fashion a new one. I worked great but hardly worth the trouble
Good luck. I'ld be interested in your solution. Keep everyone posted
Lumatic, I have a 1966 Safari. I also have a blog documenting the restoration/repair of it. One of my latest posting is of the repairs to the refrigerator vent. It is made of ABS plastic. I am a retired mechanical supervisor. I have always stressed to my crews that we were there to fix things, not just replace them. I know Andy sell a replacement vent made of fiberglass but I think I have found a successful method of repairs. If you can get the counter top off, flip it over and lay either fiberglass or aluminum window screening over the top of the crack. The coat it with plain old ABS cement from one of the big box stores. You can build the thickness up quite a bit with this method. The only downside is that the cement is black. It ill have to be sanded then painted with the Krylon plastic paint. I believe it is called fusion. I will be posting an update on my blog tonight on these repairs.

Andy's picture of that counter from the same page:
As far as that edging (at least on our 69) that snapped over it,we painted it with Krylon Fushion (the rest of the bathroom was coated with white TileDoc) in an aluminum color and reattached. Has held up for almost 2 years without a scratch (knock on wood).
Alumanutz- I will try opening up the crack big enough to get some ABS cement in there. Nothing to loose at this point.
Goransons- If nothing else works I will see if Andy has the counter. The one in the pic above has the sink on the wrong side. If it comes to that though I will be considering building my own counter.

I sure would be interested in this solution as well. I just purchased a 79 Ambassador. The crack on the counter is not a large one...but ugly....and may break down more. If Inland RV sells these...I'm ready to purchase one.
I'll try the solution NUTZ came up with as my plan B.
Trying to glue the ABS cover to a plywood support is most likely to cause repeated problems since the plywood changes size when the amount of moisture in the air changes and the ABS does not. The plywood, when it expands due to increased moisture, will pull the crack apart. It is better to use fiberglass or aluminum as a backer.
