Hiya, We bought a 04 Bessacarr E720 two berth 2.8tjd in October this year from Barron,s now Discover, in Darlington, End U lounge, 8,790 mls which is also on an Alko chassis/Fiat cab cowl and is excellent condition, I was informed it could make Any Warrantee void if I were to underseal /Paint the Alko part of the Chassis the same goes for any holes made , I dont think there would be any problem with the Fiat Chassis getting a coat of underseal or for that matter a hammer right type paint . We think the Bessacarr,s are the bees knees of Caravans / Motorhomes ,we traded in our Caravan specifically to buy a Bessacarr. We have not had the opportunity to stay overnight in Merlin as its called (so called by my son who reacons it must be Magic to make me part with that kind of Money) but have had a few nice days out ,it Drives really well , very responsive ,and considering its on a comercial based engine /Chassis doesnt roll or wallow as much as some 4x4 I have had, were planning on our first trip over the Channel in May next year, still in the process of buying things , now only need a reversing camera and then cruise control ,and later on refillable gas containers. So I will be watching with interest how you get on with your Trip over the Channel , So Good Luck and Safe Journies , Corky
