I have just discovered demountable campers in the last few weeks and looking into them.
Having sold my Defender and looking to sell the touring caravan I was looking at motorhomes.
I can tow the caravan, but not confident in backing it if I meet a tractor and trailer on a lane. My late husband used to do the fiddly manouvers and I was quite happy doing a bit of towing to spell him on a long run. I like small CS sites tucked away on farms and back lanes.
Options initially were to buy a motorhome and keep the Isuzu Dmax doublecab truck as well or a 4x4 motorhome and sell the truck. Sad option. ☹
I found a lot of motorhomes within my price range were awful when you checked the mot on the gov site even from dealers despite owners and dealers claims to how good they were. Ones that were not too big and would get up the track to a piece of woodland I own were pricey. The pay load on a lot of motorhomes was rather low when the dogs and I weigh 170kg together before we put in any supplies etc.
Keeping 2 vehicles doubles costs too.
I spotted a demountable truck camper on Ebay. All the advantages of a motorhome when driving, but demount it on a camping site for all the advantages of a caravan.
The one I spotted wasn't suitable for my Isuzu dmax double cab, but I found one that was on a specialist dealers site. After its basic weight was took off the Isuzu's payload it still left plenty of weight allowance for the essential supplies and the unessential ones too.
Cheaper than a motorhome of the same age and no double vehicle costs. I might have to sacrifice the canopy on the truck and go for a soft cover for the bed as it could be a struggle taking the hard canopy on and off on my own. I must admit I have never tried taking it off since it was fitted.
Going to see the demountable on Wednesday to see if it will work for me.
