Ordered A 200W Solar Panel Kit
Ordered a 200w solar panel kit. The price was unbeatable. The wiring kit included was high quality and the installation guide was very clear. It has transformed our off-grid capabilities. Highly recommended.
Ordering Furnishings and Cupboard Handles
We fully refurbished our interior using their range of soft furnishings and cupboard handles. The quality of the products rivaled high-end motorhomes. Excellent value for money.
Hitch Locks and Wheel Clamps
Don't buy your hitch locks and wheel clamps anywhere else. The quality is second to none. I feel so much safer leaving my van now. Plus, their guide on 'How to fit' is very helpful.
Full Awning Set
Purchased the large inflatable awning. It is an investment, but the quality is outstanding. Delivery was tracked and arrived when promised. The instructions were clear and I had it up in 30 minutes. Thank you!

Great selection of LED lighting and internal fittings. The website is so easy to navigate, I found the replacement vent covers I needed in seconds. My van looks brand new inside now!
Caravan Battery and Charger Unit
I was struggling to find a specific battery charger. Someone on a forum suggested these guys. They had it in stock. Great price and works like a dream. I’m a customer for life.
Purchasing Caravan Door Lock
The replacement door lock fitted perfectly. It is a high-security version that gives me peace of mind. Quality product and fast delivery.
Porch Awning
We bought a new porch awning from here and it is superb. The material is heavy-duty and feels like it will last for years. They even included some extra pegs. A brilliant company to deal with.
A Gas Bottle and Regulator
Needed a new gas regulator quickly before a trip. This site had the exact one. It came next day. What more could you ask for? Highly professional.
Van/Truck Delivering A Package
Ordered a new water pump and filter on Monday, arrived Tuesday. That’s what I call service. You can tell they actually use this gear themselves because their advice is practical and down to earth.
Towbar and Hitch Lock
As a full-timer, I rely heavily on my gear. This site is a lifesaver. Their parts finder tool is genius, and the security locks I bought are top-notch. Fast shipping to rural Scotland too! 10/10.

The complete water and waste kit was a great deal. It came with everything we needed for a long trip. The delivery was incredibly fast. It really made our holiday stress-free.

Caravan Accessory Box
The range of awnings is staggering. I found exactly what I was looking for at a price that was hundreds cheaper than the local dealership. Delivery was fast and well packaged. Will definitely be back for the bathroom accessories.
Used Caravan
The customer service is wonderful! I got confused with the awning size chart and called them. The lady on the phone was so patient and measured it out with me. The awning fits perfectly. Thank you so much.
Caravan Awning
I’ve been using these guys for years. They are the only place I trust for genuine parts. When my motor mover broke in peak season, they had the replacement part in stock and talked me through the install over the phone. Unbelievable service.
