  1. Jim, I also have an E-450 based class C that had a very hot floor and engine doghouse. It was a problem for our little dog who liked to curl up on the floor in front of the passenger space. I removed the doghouse (fairly easy to do - 4 clips, and then out) and inspected the limited woven insulation installed at the factory. I bought some DynaMat heat/sound insulation from Best Buy near me. This stuff is often used when installing upscale sound systems in cars. It is two layers of aluminum foil with a layer of black mastic between them. Only about 1/8 to 1/4" thick. One side has a self adhesive film which is exposed by removing a thin pull-off sheet. It cuts easily with scissors and sticks very firmly to the plastic doghouse inside surface. I reapplied the original factory insulation over the DynaMat. The work really reduces the heat transfer through the doghouse. Now I will turn my attention to the floor heat - have not done so yet. DynaMat, or other similar materials are not cheap - they run about $5 to $10 a square foot but they do work. ArtS
  2. Zorro2, I am in Bluffton SC (Sun City), not far from you. If you have had good experience with a particular repair shop, I would like to know who it is. I am going to have this fixed again but want the best experienced shop I can find. Hope to hear from you on this. Thank you. Art Sturgis 843-707-7074
  3. Unfortunately the repair job I had done a couple of months ago (replacing the rear calipers, turning rotors, replacing seals and pads, AND bleeding the brake fluid front and rear) does not seem to have fixed the problem. I took a short trip last week and the rear brakes again got very hot so the whole wheel was hot to the touch. This is on level ground - no hills. Every place I have contacted either claims no knowledge of the issue or says call someone else. I am frustrated because I have done a rear brake job and it seems not to have fixed the issue. What to do?
  4. Unfortunately I believe Wolfe10 is correct on this point. The Bosch brake recall was for Workhorse chassis only. Freightliner just yesterday told me "they had never heard of such a problem". Wow. At this point all I am trying to do is get some level of "experienced" opinion on how to best proceed. Thats why I threw the question out to this forum.
  5. I have a 2006 DynaQuest 302 with 28k miles on it. It has been well cared for. This model Freightliner chassis (M2 - 106) comes with Bosch hydraulic disk brakes front and rear. I have had a problem with the pistons in the calipers not fully releasing on occasion. My last long trip I had to have the rear calipers replaced, rotors turned, fluid replaced and axle seals replaced when the left rear caliper greatly overheated causing damage. That job was over $1,300 plus towing. Now, after my last short trip I feel the rear wheels are still hot, even in level driving conditions. My question: does anyone have experience with these Bosch disk brakes and what the ultimate fix might be? I'm willing to spend to fix them but do not want to blindly throw money at the problem? Wondering in SC.
  6. Brett, I want to thank you for passing to me the two names associated with Koni and Bilstein shocks I needed for my DynaMax. I spoke with Kevin at Bilstein and found him to be a real expert. That is just what I needed because there is no Bilstein listing for my Freighliner M-2 chassis but Kevin knew that the shocks were the same fittment as on a Safari Zanzabar so, based on his advice, I ordered them (no shipping cost, no tax, 89.95 ea) from ShockWarehouse in FL I got them a couple of days later and had them installed today. I am very happy with the improvement in ride. The "porpoising" I spoke of before is at least 50% reduced with no loss of ride comfort. I hope to say "hello" at the FMCA rally in Winston-Salem NC in two weeks or at the CAT RV rally in Kerrville TX next spring. See you there. Art Sturgis
  7. Brett, Thanks for taking the time to respond. I have had Bilsteins on my RVs in the past and think they are the best. One problem I have is the DynaQuest chassis is really a Freightliner "truck" chassis M2-106)and it appears there are NO Bilstein listings for this application. So far I have struck out although I agree with you that from shocks are the most likely fix to this problem. The rear suspension is airbags with OE shocks. It seems to be well controlled. ArtS
  8. All, On my 2006 DynaMax DynaQuest 302 ST (Freightliner M2-106 chassis), I am generally very pleased with its ride - with one exception. When cruising down the Interstate at moderate speed (55-65 mph) and I pass over a bridge crossing and if the pavement is not very level and it dips up and down (seems to be usually the case) the Dyna front end will "hobbyhorse" up and down so strongly we can almost be bounced off our seats! It seems to me to be a function of its wheelbase, heavy rear axle loading and long rear overhang that aggravates this condition. I first thought the front shocks must be worn out but they have only 18,000 miles on them. Seems unlikely. The vehicle is otherwise in first class condition, alignment right on and tires well balanced. Has anyone any insight into this "hobbyhorsing" phenomena and what would be a good approach to fixing or reducing it? Art
