ABS drain pipe vs residential pvc

[Secondmanup]

I’m installing a new sink in my RV. Like all RVs the drain plumbing is done in glued ABS. Is there an issue with using standard residential drain parts to replace the ABS? The only issue I can think of is that they are held together by clamping down with a nut. So movement I suppose can cause these clamps to loosen maybe? The old P trap was also screwed to together too. The rest of the old system is glued. It’s just seems more simple to use the residential style drain parts. Thoughts?

i just did this . sink drain pvc, then a reducer " if necessary" pvc pipe towards trap.nut first, then a ring gasket on pipe. there are 2 sizes of ring gaskets , prob the one with the least amount beveled edge. i purchased the parts at a mobile home supply since it is pvc to abs. most drain parts now ,and the easiest to buy ,converting to pvc is easy . i drew a pic. measure from top of drain to top of pipe. this is where reducers come in .
