Not familar with the dealers you mentioned but they are all starting to see this years crop of customers and the one in the store will tend to draw the most attention. Have to agree with some of the others. Since you are looking at Holiday Rambler, try an inquiry with
www.rv007.com
On the "contact us" make your inquiry and ask for James Silvey, he has been very open and helpful with us. or JAMESRV007 on facebook.
And with them you shouldn't have too many surprises, all pricing is upfront and no add on fees at the last minute.
