Truly great prices and even better people!
From start to finish the very patient folks walked us through the options that made sense to our family. Unlike other experiences they were very transparent and highly communicative throughout the process.

Katy from Scottsdale, AZ
We bought a trailer
They were so knowledgeable and friendly .

Justin from Florence, AZ
Great experience with Anne and Royce (everyone was great)
Everyone we met was friendly, helpful, and knowledgeable. We are ready to take delivery and do our orientation. So far we have had nothing but 5 star treatment and would recommend if you are in the market come take a look at LDLP before you make a decision on anything else.
