Hmm, my entire broadside tends to consist of laser cannon...
Or, dispense with the wimpy truck altogether, and load your mecha down with five dozen tons of truck fodder you have to safely bring across the map.
You could assume it's sixty tons, of, say, chocolate bars, which would inflate your (and raider) PV by about 30,000,000. Also, your MV, TR and dpr drop a lot so it wouldn't be wise to do this job in an aerofighter. Well, whoever heard of a five-floor mecha dogfighter delivering chocolate bars anyway?
