Perhaps there's a 4:1unun inside, and the designers (or the sales types, or both) either don't know the difference between an unun and a balun -- or they don't think most hams know the difference (in which case, they're right about the hams). But there is a difference. More than one small output has made ham antennas with ununs inside and mistakenly called them baluns. Many screwdriver-type mobile antennas contain ununs that the dodo-bird marketers call baluns.

In that case, it could be a reasonable match at some one frequency, but need a tuner anywhere else.

But there's still a mystery in that 30-foot-minimum feedline --

As far as the 30' coax is concerned... I keep 50' in the trailer all the time anyway

Here's a 6 month too late option: Hamsticks (2 for each band) configured in a dipole fashion, on a fiberglass telescoping pole rock! I use this config all the time on the road and I have zero regrets. I even have the bottom section permanently mounted to the RV ladder (I have a similar section at the home QTH) so I can change the antenna/poles to the RV or home in an instant. The dipole config also alleviates much of the counterpoise problems associated with a vertical and is quieter. If you need a bit more bandwidth than you've tuned the sticks for the internal tuner will give you some.
