Hello all' I am brand new to this sight but love these little motor homes (especially with the price of gas). I have recently come upon what I think is the deal of the century but I am not very experienced yet to know the values. I found a 1977 Chinook with 53000 miles on it, the body is good aside from some faded paint but no rust. The frame is also in very good shape only very minamal surface rust. The interior is clean and everything functions as it should. The current owner wants $1200.00 for the little rig which I thought was very reasonable. They told me that the weight of the mh made it slugish going uphills but it does great on the highway. I have asked around on some internet sights and have been told that a cam, carb, header, and ignition upgrade will make a huge difference and not affect the fuel economy. Has anyone out there done any of these mods, and do they really make a noticable difference? Is this a good price? Also the tires will need replaced, now there is a set of bfg's on it that are dry-rotted. What kind of tires does a chinook take as far as load range? is a load range c or d to heavy of a tire that will make the ride too rough? Any help will be greatly apriciated.
