If you run into trouble with your local department of motor vehicles in changing the title of a class 8 truck to be a motorhome, you might look this text over:
Effective Date Note: At 67 FR 79439, Dec. 27, 2002, Sec. 571.3(b)
was amended by adding the definition of ``motor home'', effective Dec.
27, 2004. For the convenience of the user, the added text is set forth
as follows:
Sec. 571.3 Definitions
* * * * *
(b) * * *
* * * * *
Motor home means a multi-purpose vehicle with motive power that is
designed to provide temporary residential accommodations, as evidenced
by the presence of at least four of the following facilities: Cooking;
refrigeration or ice box; self-contained toilet; heating and/or air
conditioning; a potable water supply system including a faucet and a
sink; and a separate 110-125 volt electrical power supply and/or an LP
gas supply.
The GPO web page for this section 571.3 under Title 49 can be seen here:
Code of Federal Regulation Title 49, part 571
The Feds do require "uniformity" of title information based on US Code "National Title Information System" if that helps your case any ! Please note: the definition doesn't go into effect until Dec 04.
Good luck,
