We have an 8.3 Cummins in ourRV and rebuilt itlast year. It had one liner fail. Since we were paying a shop to do it, it made more sense to us togo all out and do all new liners and piston kits. The sleeves push out. They might have been able to do it in frame, but they preferred pulling the engine out the back and rebuilding it on a stand. It looked pretty straightforward. I think any engine with the removable sleeves is a smart move. I would see if you have a connection to a local shop familar with commercial diesels. They will tell you the pros and cons. None of the toters and rvs take the abuse the work trucks do. If they survive that torture, then it won't be a problem for a toter. I would look at the maintainance that was done. Some of the toters I have seen got zero upkeep and just a lot of run time. That can come back to haunt the next owner. One thing is the ph of the antifreeze. If it is not monitored, it can ruin liners or in the case of a cat for example, cause pinholes in the cylinder walls.You do need to know how much a total redo will cost and decide if you can stomach that if it comes up.
