I too purchased from ExploreUSA in Seguin and my experience was a mixed bag. I was initially very impressed with the staff and their customer service attitude but by the time we finished the sale there were some disappointments and serious concerns about their integrity. After the sale I had some minor service issues taken care of at another dealership (out of state) and received fantastic service. However, they said they had great difficulty dealing with the Seguin staff regarding my unit. Of course the Seguin staff denied all the allegations but I also had problems myself with followup issues with the Seguin staff and came to the conclusion it was the Seguin staff causing the problem. Overall I'm satisfied with my purchase from them but there is still a bad taste in my mouth.
Here is my opinion after all is said and done. It doesn't really matter which dealership you deal with as long as you do your homework and absolutely know what you're doing. Never take the dealer's word for anything. Research prices across the Internet. Check specifications with other sources. Spend lots of time reviewing your intended unit on this forum and ask lots of questions. Go to Heartland's main website (
www.heartlandrvs.com) and find every piece of information you can on the unit you're interested in. Call Heartland and ask their service department questions. When you finally do negotiate with your chosen dealer you will be in a position of strength and you will feel more in control. They will be less likely to take advantage of you.
When you walk through the unit at the time of delivery make certain you examine every inch of the unit for visual damage and proper function and document all issues on the paperwork. Take photos of any damage. Turn on/off everything and make sure every switch/light/appliance/tap, etc. (inside and out) works correctly. If not, write it on the paperwork and get a written agreement that the dealer will be responsible for it.
If you find the most honest, trustworthy dealer in the country things can still go wrong and mistakes can happen. Bottom line... don't "trust" the dealer for anything. Protect yourself and you will be much happier in the end.
By the way, Heartland was my choice above every other manufacturer on the market. I did my research.
Good luck in your search and eventual negotiations!
