The starting price is only the starting point.
Compare the version you would actually take camping. A frame, a camper kit and a finished conversion buy very different things.

Put the essentials in the same basket
List the selected frame or kit, a suitable mattress, storage, lighting, ventilation, power and any cooking or water equipment you need. Mark every item as included, optional, separately sourced or still unknown.
Bring it all the way to your door
Add shipping, import charges where applicable, tax, installation and travel or transport to the builder. Ask what happens if a kit does not fit and who pays for return freight. A seller quote is more useful than filling missing costs with zero.
Keep the vehicle budget separate
A kit price usually does not buy the van. A trailer price does not buy the tow vehicle. Keep the vehicle purchase, inspection, maintenance and registration separate from the camping setup so neither disappears from your plan.
Budget for using it, too
Campsites, fuel, insurance, storage, repairs, connectivity and laundry can all matter. Start with your own expected usage and actual quotes. Avoid treating a camper purchase as a guaranteed saving over rent or holidays.
