warranties are part of the profit centre for dealers. the issue is that the chassis is Mercedes but the house is Triple E (Leisure Travel Van) in Manitoba. Most of the fix it things on our 2016 Unity so far has been the LTV components not the MB components. Like batteries; propane service, tires, wheel balancing etc...
Check to see if the recall has been done on the exhaust. The Sprinter forum has lots of info when you do a search. That extended the warranty for 10 yrs.
Unity | Sprinter-Source.comI have only had the Sprinter at the dealer once for the recall - the other things are at an RV dealer and at tire shops including getting the oil changed at a truck tire shop.
I do have a full set of tools for the job though so the small stuff I have been doing myself. and I got 4 bolts for the driveshaft with a socket that will fit the Torx bolt so the driveshaft can be dropped for a flat tow by any wrecker. I got the bolts at an MB dealer - there were about $1 each. They are needed because the one you take out can not be resused when they put the driveshaft back.
for the ladder see if the bottom part is there as there is an extension that came with the original.
Check to see if they changed the chassis battery and if the voltage is at 12.7V - you can test from under the hood. It takes a torx T15 to get to the battery in front of the drivers seat.
