Went to look at an Adria Coral 660sp today. Nice clean vehicle and looked after. Surprised not to find an oven in the van. 3 ring burner and grill so how do they do all their cooking. Is it possible to retro fit a cooker. Theres a big drawer under the hob which can be taken out and a cooker fitted in. Possibly a bit of a faff and expensive though. Any thoughts wise people?
