Customer Reviews
Caravan Awning
June 19, 2025Purchased a caravan awning in march, very good quality and value for money. Easy to assemble, no issues. Company very helpful and attentive when i had to email them. Will go back and purchase other items from this company .
Sheffield Branch
April 14, 2025Went into the Sheffield branch today to buy a drive away awning for our campervan. The service we received from Tom was outstanding, his knowledge was incredible and nothing was too much trouble for him. Well done young man it was a pleasure to do business with you
Did Some Magic This Time
January 15, 2025Close to home so a walk for most of our caravan bits. Bought virtually everything there in the last two years we have been caravanning, inc. awning and tow bar fitting. Price wise they are always competitive.
Our visit today was a step beyond the usual service we have enjoyed from them.
Tried all over the internet for a removable weather cover for our tow bar with hours of no luck, so we had a walk to shop and as it's discontinued it was looking grim. They had a look on internet and offered a makeshift solution before having the idea of searching their old parts bin just in case. Well surprised and chuffed to find they had one (think they was as well). Thanks David and Steve for the excellent customer service.
Fantastic Service
October 17, 2023Fantastic service from start to finish! Great guidance on the correct items to order and how the process works. Really appreciative of a great service and advice, parts arrived quickly and the fitter arrived at our house to do the work on the driveway as planned. Very happy with the result, thank you so much. Will definitely recommend you!
Easy From Start To Finish
March 11, 2020Ordered online and the towbar came to the house , Caravan Auto Shop was incontact to make sure it had arrived and a day for fitting.
Closer to the fitting day the fitter was in contact with a estimated time they would be here , came at time they said and took about two hours to fit towbar and wire the electrics , it all works as it should 👍
