What a great site to learn important maintenance stuff.. Today I opened up the ac condensor cover on the side of our 04 Holiday Rambler Endevour 40DST and found it to be quite cruddy.. I also found the 2 fuel filters staring at me
.. So I used some cleaner/degreaser, similar to Simple Green, and soaked the coils and fan assy.. After a few minutes I hosed it all out and the crud came running out.. I used soft water to wash it out.. We bought this rig last April, Thanks for the tips from this forum
