I've had a 13' Boler
and currently have an 18' Esterel (a wierd, solid sided French-built pop-up. Photos are on my photo site. Linky in sig).
Anyway - I can't point-blank say one or the other is better. One is better for some things, the other is better for others.
I like very much being able to garage the trailer when not in use. That's normally a nod to the pop-up, but my Boler
was REAL short and WOULD roll into our garage (barely).
I DON'T like dealing with all the set-up/take-down associated with the pop-up. Heck, and I don't even have tenting and slide-out bunks to deal with!!!
Storage was better in the Boler
. Pop-ups have lousy storage because they have to fold down to nothin' so almost all their internal space it taken up by themselves (beds, kitchen stuff etc). I find the lack of decent, convenient storage in the big pop-up trailer somewhat irritating. The only really decently sized storage is the underseat areas - which is a hassle to access usually. I'm kinda a storage space nut though. Check out the PlayPac rebuild if you have any doubt.
Boler was cuter. Anyone who doesn't agree with this statement should be banned from the list.
Are ya single? The Boler attracts women. No kidding... I wasn't in a position to take advantage of it - but we got comments (good ones) and questions about it nearly CONSTANTLY from women. I can't possibly be the only one who's noticed this...
A 13' egg will likely weigh less than any pop-up you can buy. All that pressboard is heavy stuff!
Given your statement of "many miles with short stays" - I'd think that the set-up/take-down involved in a pop-up would get tiresome. To be honest - the big factor that moved us into the wierd Pop-up was partially the overall size (about the same as a big egg) but mostly the size of the rear bed. Our Esterel has a true queen in the back while the Boler's bed was 44/48 inches wide MAX (ignoring the curve). That was the real deal-maker. Someday I'd still like to get a beater 16' Scamp
and rebuild the interior to have a bigger bed in the back.
If I was looking to fit a really big family in the trailer however - I'd be looking very close at the larger pop-ups (normal ones with the slide-out bunks that is). That's where you get small packages that sleep 6 or more easily. That kinda capacity is hard to pull off in an egg (Casita Spirit Standard with double-bunk option is about it).
