Like thor and forest river, they are low end.
The only damon i ever looked at seriously was so low end as to not be considered.
In a lot of cases, ie ford v10's, they are all really close regardless of nameplate, with others, such as forty foot DP's with isb drivetrains and the cheapest possible frieghtliner chassis, not so much.
The Damon daybreak I test drove before buying a 1999 fleetwood pace arrow (for 30k) was HORRIBLE.
