From documents I've found, we know that Mobile Scout Manufacturing Corp. was building Mobile Scout campers in various lengths and configurations from the late 50's through the 60's. Camper building back in that day was a bit different from manufacturing today; given the variety of interiors and structural details, they appear to have been built with whatever resources were on hand -- the framing in ours, which we exposed when we took the skin of and the interior out in order to replace some rot -- was clearly whatever wood they had around, some clearly recycled. I've never been able to pinpoint how many of these vintage models were produced.
A postcard does suggest that they were booming; an ad-postcard for Mobile Scout Manfacturing Corp notes their Arlington, Texas address and the opening of a new plant in Pennsylvania (circa mid 60's?).
The old logo is confirmed in a bumper sticker that is for Mobile Scout Manufacturing Corp in Arlington, Texas. Ads in vintage camping magazines show a variety of lengths and configurations.
The trail goes somewhat cold, until SunnyBrook RV starts making travel trailers in 1992 under the SunnyBrook and Mobile RV names. A Google Image Search also finds some 90's campers that have the vintage Mobile Scout logo with "by SunnyBrook" beneath it.
I've not been able to ID what happened or when. Letters to SunnyBrook seeking someone in the business office who might be a vintage camper buff have so far been unfruitful. Finding someone in Arlington, TX who is from the era gets increasingly less likely by the day.
If you have any history information, please get in touch with me. I'd love to find out more.
