Kirk: I was referring to Monaco's Motorhomes. In 2002 I toured the factory and asked that question. No, there were no engineers on staff. I was told they outsource. Other MH manufacturers buy their chassis from Freightliner who do all the engineering. BUT most RV mfrs. do have some journeyman electricians in order to comply with RVIA codes. What makes you think that an engineer is needed in a trailer factory. If the chassis is built elsewhere it should be engineered to do the job. The RV mfr. is simply bolting down a floor and installing walls and roof. If you have ever seen an RV in an accident it looks like it was made from toothpicks. They literally fall apart. There are exceptions: Both Marathon and Country Coach did have engineers. AS did Winnie. I don't think Tiffin does.
