the dreaded tire topic...

The sad part is, running gear upgrades do not show up in too many camper brochures. You can not sell it, if it is not offered. Some are finally coming with rubber equalizers, shocks and I even saw self adjusting brakes but they are far and in-between. I have yet to see an adjustable axle seat even though they have been around a long time. And they still keep using these light duty hangers and frame attachments.

Just maybe RV trailers are built to the specs required by their weight and usage factors. The engineering analysis for RV trailers does not require a background for self propelled vehicles. Engineers for the RV trailer industry come from the same schools as those designing cars and trucks.

Take a look at pages 27 - 30 in the reference. Looks to me like that's a pretty good explanation of a simple system to support an RV trailer.

Hi FE,

Thanks, that is one nice camper. Boy, thats a beauty. Mobile Suites I would put in the high end RV trailer. And in that type of quality, upgrades come as standard.

From the catalog you posted. Things that caught my eye.

First the tires, using their words

Mobile Suites wrote:
Heavy-duty 17.5" Goodyear® tires provide
increased load capacity while staying cool on
long hauls. We use truck tires, not RV tires, to
ensure better performance and peace of mind

Note the truck tires note.

They have oil bath bearings.
They have greaseable suspension bushings with grease fittings.
Kodiak disk brakes
15 in. wide stacked structural tubing frame. That is a big difference.
Extra frame cross members to not twist the frame rails.
8,000# axles. I cannot find the GVWR specs but assuming a triple axle is still at or under 25K. I would think over 25K may push the need of a CDL.
They use Mor ryde IS suspension. A totally different league than most TT's

When you used the words "simple system to support an RV trailer" what is on that Mobile Suits 5er is not what is on the majority of TT's.

I have great faith that the RV engineer can build a quality TT RV frame and running gear system and it will not cost that much more then what the average TT build when purchased at the OEM level. This all comes down to $$ and who is making it. That is fine, offer it to the customer, tell them the advantages of why and they might just buy it. Or will it open up all the questions of why don't they just include them?
