PS--All Alpines require brake fluid change and flush every 2-3 years. For older Alpines, bushings on front and rear hardpan [track] bars should be checked. Kitchen sink drain connection under shower pan should checked for leaks. Check the upper seam on the exterior belt line [sidewall/basement] for cracks in caulk, also the basement ceiling next to beltline for water intrusion. Does it have a 2-speed jake brake setting? Check to see if fuel lift pump above starter on engine is leaking, side of engine will be wet/grime. Again, a well care for 2003 will be a great find....Keep me posted.....dean
Hey Bob, I think the 2003 era Alpines are some of the best units made by WRV. Fairly straightforward to work on, no Vansco, and the ISL is a sweet engine. If properly cared for, the 2003 will give you many miles of enjoyment--we had almost 200k on our 2003. There were a few changes in 2003, the later models had a 33k suspension and a better wheel cut. Yes, with the wax valve, the dash air is a challenge, though some owners never complained. HWH hoses were an issue in 2003 but should have been replaced by now--especially the wardrobe hoses over the radiator.
