Before asking this question, I'd like to give you some background.
I've ordered a new 2005 CTD 3500 QC LWB 4X4 Dually. Due to the new suspension setup, the back corner of the bedrail sits at about 60" off the ground. My 2001 sat at about 57". When my trailer is hitched (on my 2001), I have about 5 1/2" of clearance between the trailer and the top of the rails, tailgate, in the back. This has been adequate for the type of towing and camping we do, and the 5th wheel sits almost level.
I have discussed doing a springover, for my Alpenlite trailer. MY RV fab shop can do it but they suggest that I wait until the new truck gets here, and see how much the rail drops, with the king pin weight on it. In fact, Klenger (fellow TDR member) has stated that he thinks his new CTD compressed more than his pre 2003 CTD. If that works, that would be great, as it would save $300-$400 not doing the springover.
The only problem with this is that after the new truck arrives, if it doesn't compress the rails enough, I won't be able to tow the trailer to the fab shop for the mod.
I would like inputs from fellow TDR members but only if you meet the following conditions.
2003-2005 Dodge 3500 QC LWB 4X4 with tow package; No mods to suspension of the truck (i.e. not lowered, no air bags, etc.); a king pin weight of 2000-2600lbs. I'd prefer Dually info, but a SRW 3500 might also be valid.
1. What is your rail height at the rear end of the bed rails with no load?
2. What is your rail height at the same location with the trailer loaded (level ground)?
This would be helpful for me to decide if I should do the srpingover now, or wait and see after it arrives. I can do it now, as I still have access to my 2001 to tow it in to the fab shop. Thanks in advance for your help...
