Thanks for welcoming me to your forum and for responding to my questions. I hope the following is not too long.
I would like to know more about the problems with the isx. I have been told that there are less problems after about 2012. The few folks I know with them seem to like them. Although most Truck owners and equipment operators seem to like the cat better. I have a couple of Cummins M11s but they are in dump trucks and pre 2002.
I bought the 07magna Rembrandt 630 two years ago September. It had 19,0000 miles It now has just over 50,000 miles. (at 4miles to the gallon you can do the math) Like I said above I have less maintenance per mile than I had with the Beaver. Further, at 54,000 pounds, with a good length to wheel base ratio and impressive dynamax chassis it is great to drive at free way speeds and it handles our Wyoming winds very well. When it comes to snow and ice I have ben very impressed. I am sure there are others but I am the only one I know who carries tire chains in the RV and I have used them more than once. The additional wheel base ratio (or something) makes it much better on snowy roads and in the wind compared with the Beaver. In summary, I think the CC Magna is one of the best coaches out there and I am not going to trade it for a different brand or model without exhaustive inquiry. But, if I could keep the things I like and obtain better mileage and the extra half bath I would be tempted. I might even consider owning two for a while. That is what I did When I Bought the Magna. After several months I decided it was the 01 Beaver Marque that would have to go even though it got better mileage and had the 2nd half bath. (I guess I just want the best of the two and that may not be out there)
I think the c13 ( which is set at 525 HP) is a great engine but it should get better mileage. A friend of mine that has several trucks swears by the cat engine but he says the c13 is thirsty and that having it set at 525 causes it to be wound up relatively tight at any given torque as opposed to the c15. He thinks I would get better mileage with the c15 because the engine would have a higher torque at lower RPM. Of course there are no cornerstones with the C15 I am only aware of a few Affinitys, Magnas and Beaver Marques with the c15. If anyone knows of a well built coach with a c15 I would like to learn about it.
I thought the increased emission regs were in 08 is that correct? I think I have about exhausted the legal avenues to address the mileage issue. I have taken it to cat for engine diagnostics, put it on the dyno rack and worked on the exhaust. Any one reading this probably wants to advise slowing down as that would help the mileage. However, I drive it the same as I did the Beaver.
I did a lot of research before I bought the CC Magna 630. It usually shows up as one of the safest, most road worthy and well built coaches. I did not look at fuel mileage because I figured it would be similar to the beaver at about 6 mpg and I was mostly focused on road stability and ability to operate in the cold.
I looked at Newmar which I think makes a good motor coach. The Essex and King Aire have highway ratings as good as the CC but the Essex I looked at did not have a big engine and I never found a King air at a price I wanted to pay.
I have not been in a Bluebird but I will look into them, There does not seem to be many of them on the secondary market. (I am a confirmed 2nd hand coach buyer the day one depreciation on a new one keeps me awake at night) I have a couple of Detroit engines but they are older and in construction equipment so it is difficult to compare
I have not been in a Fortravel but I would like to learn more about them.
I have been in a few Newells, They are very fancy but for the live of me I can not see why they cost so much more than an Affinity or Magna.
I have decided that I need to look at Alegro, particularly the zephyr. However, I met a fellow (Al) from Maryland when I was in Indiana who drove a Cornerstone. we visited for several hours. Al had owned a Tiffin and an American Heritage, he raved about the Cornerstone and said it was a much better coach for the money with less trips back to the factory than either of the other two. However, he has never had a CC Magna or Infinity so he could not compare the two but my conversation with Al made me decide I should look for some one that has owned both a Cornerstone and a CC Magna or Affinity that could compare the two based on experience. For example, I would like to ask how does the newer freightliner chassis compare to the dynamax? And will the Interior of the cornerstone hold up? It appears to be less sturdy then the Magna to me but my impression was based on minutes as opposed months or years
According to Consumerrv.org, the Cornerstone is the equal of or slightly better than the CC when it comes to road worthiness. The information from that organization led me to the CC Magna and it has been great other than mileage. Accordingly, I give some credit to their ratings. on the other hand I talked with the owner of an RV repair business in Oregon the other day, he use to work at Country Coach and he is a fan. We only spoke for a moment but when I asked him about the Cornerstone his brief reply was that Entegra has a great customer relations program which he said is a good thing since they have problems.
