Yeah, there was a thread about this recently. 'Tis a crying shame that the CRV, a very popular choice among MH owners wanting to flat tow, is no longer able to be towed that way. Like you said, the choices of vehicles that can be flat towed without major modification is getting smaller and smaller.
If you really like the CRVs, you might want to look for a lightly used CRV model that can be flat towed?
