Tandem vs. Single Axle

Just to note the part that failed on my single axle trailer was the pole tongue...not the axles or wheels/tires. I think that part of the problem was that I was towing with an "air ride" RV and it didn't follow the dips of the roads--the trailer did. There are some big bumps in Mississippi (where it failed) as well as in LA on I 10. A lot depends on the vehicle's suspension and wheel base as to how much it will affect ride.
 
While in FL I called the trailer mfg, Rocket Trailer, and spoke with their tech. It turns out that I can not add an additional axle they mfg as there is not room on the frame. From the bend to the rear of the frame is 6' and he said I needed 8'.

This assumes adding one of their axles that are attached to a piece that can slide forward and backward to adjust where the axle sits on the frame.

I still might go to the local trailer place and see what they say.

Came home with no problems.
 
I could only find load range D for my 14" rims on my CD trailer, I could get load range E for my 15" (10 ply) for my Tug trailer tires. I would love 15s again.
 
One has to remember that 15" wheels come with 5 and 6 lug nut patterns. The 6 lug nut can have a higher capacity. (And not all bolt patterns are the same.).
 
Bob, that's the problem, 15s would need new axels (torsion type) new fenders and raise the the rollers up a half inch, it just isn't practical, I bought new 14" tires for the trip so I could go from load range C to D (very few choices) and they handled the trip fine, even with a couple of miles of washboard dirt road and a few unavoidable potholes. I think I may be overkill excessive
