Henderson's has to be about the best place around for professional work for suspension upgrades to your motorhome. The road test really points out what the issues are that need to be corrected. Henderson's then gives you a prioritized list of items that will correct the problems you are experiencing. Like a soup to nuts offering of which you can choose some or all to be be done. We went the full list on our coach and I could not be happier! We were also able to stay in our coach overnight, plugged into 30 amp service in front of their service bays which saved on hotel expenses and eating out. The waiting lounge is well appointed and comfortable. What I really liked was that the service staff gave full explanations of what was being done, kept you apprised of repair status start to finish. The owners, Robert and Barbara are wonderful people, and treat their customers with total respect. If something is not quite right, hey strive to make it right. I can't say enough good things about them and their staff. Oh, and the ride hoe - well, it was a pleasure! We took the same route back using rough, windy roads and I could not believe the difference the suspension upgrades made in the performance and comfort levels - no swaying, bouncing, wife having to hold onto the seat in curves, etc. We are both extremely pleased with the end result and highly recommend Henderson's for the quality of their work and the end result! We now feel that our Tiffin Open Road is safe to be on the road!
