Why don't you run the numbers for the OP and tell us what load his floor is capable of withstanding? Span tables and calculators aren't helping, since they assume shitty #2 modern dimensions.
Iím accustomed to using MSR lumber in the truss industry.
So, itís all of know species and moisture content.
Iím not sure what grade of lumber (or species) heís got.
And like youíve stated, thereís an equally important issue regarding the connection of the joists to the main beam.
Also, what supports the beam? Columns, multi-ply post, CMU, steel ?
With modern eng trusses, the concern isnít really then trussís ability to perform from a structural standpoint, but the vibration of the vehicle can/will jeopardize the joint plates.
Moving the trailer creates a moving load, which is pretty significant.
I guess Iíd leave the trailer outside. Cuz, itís a trailer.
