We have taken our 28DSBH from Ontario to PEI then all the way to Vancouver Island and back to Ontario. So far I have 17,000 kms on it and as previous posters mentioned just do routine bearing, brake and suspension maintenance and you will be fine. I did have the nylon suspension bushings replaced with brass as the nylon wore out after our first season. The brass bushings have grease fittings so they should last a lot longer.
