And this is why I gave up my beautiful diesel pusher and traded for a Class C.
The breakdowns on the side of the road ( 8 engine disabling breakdowns in 3 years, and $40000 in warranty engine work in 3 years.) At some point these specialized class a diesels and class a gas rigs are just not worth the heartache. The hard access to specialized engine components is what does them in.
A new fuel pump for my diesel pusher parts and labor was $7000 and 1 week on side of road waiting on part. Access was extremely difficult. A new one for my class c Ford is $94 and I can go down to the local AutoZone and have it in 5 minutes and spend another 10 putting it in myself.
A new special order leece neville alternator for my diesel pusher cost me $2000 parts and labor in remote northern British Columbia (no warranty) and 1 week of sitting in my rv on the side of a tiny road watching bears walk around the rv and breaking into trashcans until fixed. Access to the alternator took both me and a mechanic and was extremely difficult.
A new alternator on my Ford class c would have cost me $100 or so and I could have driven back to the Napa in Watson Lake.3-5hours away in my tow car and been going within the day. I could have changed it myself.
The nearest alternator for my diesel where I broke down was 24 hours driving time away one way in Edmonton, Alberta. They literally flew my part into me in a small plane at local airport all the while coordinating this on a $2 a minute payphone 25 miles away from where we broke down. (No cell service) RE FREAKING DICULOUS!
Just my experience. I loved my diesel pusher, but at some point, the heartaches are not worth it and simple, standardized mechanical parts and access is best.
