2wd to AWD conversion

[Manitou001]

Sorry if this is the wrong section of the forum.

I've gathered that if you want awd, then buy one with awd. The conversion isn't generally "worth it". But, I am looking at this tiger rv.

The rv conversion suddenly makes it worth it (in my opinion). I have never taken in such a big mechanical change though. Is there instructions somewhere? Maybe better yet, a shop that will do the conversion correctly and for a reasonable price?

Thanks!

Get a AWD parts van, swap the sub frame.
