Hi - FWIW, we just moved to a B+ from a B. One of the units we looked at was a Thor Citation - "cousin" to the Siesta. Were REALLY disappointed with the build quality - big things, like how they extended the chassis under the unit with un-finished steel - already very rusty... Ended up with a Coachmen Prism - MUCH better build quality for equivalent money. Just my opinion, but do look closely at the "meat and potatoes" of the unit to form your own opinion. Too bad, too, we really liked the Thor layout, but must say were are VERY pleased with the Coachmen. ST
