Owners of Dodge based RV's?Hello All, I am new to the RV Scene. Bought a 1979 Dodge Tioga Class C. I have had one thing after another trying to get the thing smogged. Finally passed after I caved and took it to the mechanic. Turned out just needed a carb tune up. I took it on a short trip after which it melted a spark plug wire. Replaced and was on my way running not so great. Replaced plug in question tonight and notied the number 8 wire also was melting around the boot. Now I am really concerned. Number 6 and 8 are running extremely hot and melting wires. I doubt I will make it to my next destination of any distance without melting more wires. Could it be my exhaust manifolds are bad, clogged or something? Anybody else have this problem? PLease help!
