Self Directed Ira - Is a purchase of Travel Trailer allowed

[Chris Goon]

If a person already has land/lot through the Traditional SDRIRA, would the purchase of a mini travel trailer for that lot be allowed under the SDRIRA?   The intention is to rent the unit.  In my area the growth and demand for a little land and fresh mountain clean air & water is exponential.  I figure it may be worthwhile to get the monthly earnings back into the SDRIRA this way. The acquisition cost is fairly small, compared to the potential earnings.  The reason I ask is that it is technically a recreational vehicle, however its going to be rented on a lease agreement for 6-12 month basis.  Would that fall into a rental home category?  or would that even matter.
