Well Wilma there is both good and bad news in that story.
Very sorry to hear of your loss,, Sounds like the RV is your home, but.. Engine repairs can be anything from minor (less than 100 bucks) to major (Several thousand) and with the RV totaled, and the pick up driver being clearly at fault... Well, you may well come out of it able to replace most of what you lost in the crash.
or.. Well, I'm looking for a co-pilot (Not really serious since I do not know you) the problem here is that I need a MAJOR engine repair (Replacement) which won't happen for a few month yet.
Or like the old joke
(WWM seeking traveling companion Single/widowed W F with JEEP, Send photo of Jeeep) (And I do stress that that's a joke)
Again, Sorry to hear of your loss. Glad you were not injured.
