I have a 2005 38ft dp with two slides. I have owned it for a year and a half and have driven from Akansas to California and back towing a buick enclave. We have been living in it since august on a small trip and have hit weather this winter down to -4

I love my coach. Issues I have had is overheating. I honestly think the radiator is too small for the unit. If you do some research you will find that freighliner did some work on units trying to fix the overheating problem. They did not do a recall they did a fix if you brought it in and complained. The fix seems to be they changed the hydraulic fluid that powers the fan from hydraulic fluid to motor oil. When they switched they had a problem with the pressure generated by the motor oil ruptured the cooler. I had a problem with my coach when I went across the Mohave desert in August. When I started going up the hills on the other side the temp was about 106 degrees outside and my coach started getting hot. I could gear down but a couple of times I had to go down to second gear. It is a bit annoying to be pulling a mountain at 35 to 40 miles an hour to keep the engine cool. I had enough power to go up the mountains but in 6th gear the engine rpms were too low. I took my unit to freightliner and they decided my hydraulic controller was not bringing the fan up to full speed. They replaced it and I have not had a chance to go up big mountains in hot weather since to check it. I did check and I have hydraulic fluid in my unit although I have a sticker on the filler neck that says fill with motor oil. MY next step will be to call freighliner with the vin number and see if they have changed the hydraulic fluid cooler to one able to take the higher pressure of using oil.

The other engine problem I have found online is that some 400 ISL engines had a problem with the wrist pin which connects the piston to the Rod. Some of these were installed wrong and can come off creating a big issue. There is a recall for this and they have published the serial numbers of the engines that were involved.

That is the negative side of it. I like the floor lay out and love driving it. I am not sure what they did different but 2006 models do not have the spectre of overheating.
