The Allen Family has a one-off TLC special that was just recently shown on UK tv. They're another singing Missionary RV family, like the Rodrigues and Willis families, and the show was as weird as you might imagine, with tons of emphasis on purity, bus life as a family of 12, homeschooling and children having to sing for their supper. They've featured on FJ before, most comprehensively in this thread:
Basically, they seem to be a much more polished and successful version of the Rods, and Jill Rodrigues must be jealous as anything (though while they were certainly grifty, never on the level of grifting a whole house) - and they had a tour bus where they slept 13 and ALL THE CHILDREN HAD THEIR OWN BUNK!!11!!!1!!111!!
Their blog is hard to follow because their writing styles are pretty bad, and they don't date their entries, so they may or may not be missionarying in Uganda right now, but surprisingly for griftionaries, they've been involved in some actually useful projects, like raising cash to get sanitary products for girls, so they can attend school while on their periods. I especially liked the upside -down photos....
They had their own YouTube channel, but I couldn't watch - the "comedy" gave me terrible second hand embarrassment, but their singing is pretty polished. I'm a little bit confused about how singing to churches is a Mission, as that's pretty much exactly "preaching to the convertd", but their show seems pretty slick, and they look like they're having fun when they do it.
The older daughter Gabriella had a very smug SAHD blog, but her twitter is now all about shilling MLM with her sweet husband
(They're also economical with the truth - Gabriella said on her wedding site that "I travel the world with my family 365 days a year", and in the TV show they claim their oldest son and his family live on the bus, though eagle-eyed FJers spotted the fact that a) they blogged they were off the bus for 5 months that year, and b. they blogged about going to visit the older son in his house...)
One of the boys, Jared, is choosing to wear a tie every day because he's always in the presence of God (it makes him stand out in a huge family) and has written a book about his life:
